    Samsung Workers Strike, the First in the Company’s History

    The South Korean tech giant is at odds with some of its employees as it is trying to reassure investors that its memory chip business can meet demand.For the first time, workers at Samsung, the conglomerate that dominates the South Korean economy, went on strike on Friday.The action comes as Samsung Electronics fights to regain its edge in the business of making memory chips, a critical component in the advanced artificial intelligence systems that are reshaping longstanding rivalries among global technology companies.Workers in Samsung’s chip division were expected to make up the majority of those who will not report to work on Friday for a planned one-day strike. Union representatives said that multiple rounds of negotiations over wage increases and bonuses had broken down.“The company doesn’t value the union as a negotiating partner,” said Lee Hyun Kuk, the vice president of the Nationwide Samsung Electronics Union, the largest among five labor groups at the company. It says that it represents 28,000 members, about one-fifth of Samsung’s global work force, and that nearly 75 percent voted in favor of a strike in April.Lee Hyun Kuk, vice president of the union, said the workers aimed “to send a message to the management that we have reached a certain level of maturation.”Tina Hsu for The New York TimesMr. Lee said that union workers received no bonuses last year, while some had gotten bonuses of as much as 30 percent of their salaries in the past. “It feels like we’ve taken a 30 percent pay cut,” he said. The average union worker earned about 80 million won last year, or around $60,000, before incentives, he said.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    South Korean Election to Set Tone for Remainder of President’s Term

    The vote Wednesday is a big test for President Yoon Suk Yeol, who has forged closer ties with the United States and Japan but whose domestic agenda has stalled.In the two years since he was elected, President Yoon Suk Yeol has made his mark in foreign policy, forging deeper ties with the United States and Japan. But his business-friendly domestic agenda has been stalled by his own missteps and an opposition-controlled Parliament.Mr. Yoon has a shot at a do-over on Wednesday, when South Koreans head to the polls to ​select a new Parliament.Dozens of parties are vying for the 300 seats in the National Assembly, South Korea’s single-chamber legislature. However, the contest is largely between Mr. Yoon’s conservative People Power Party and the main opposition camp, the liberal Democratic Party. Both have intense followings, but the eventual winner is expected to be decided by moderate and swing voters.This is the first general election since Mr. Yoon won the presidency in 2022, beating Lee Jae-myung of the Democratic Party by a razor-thin margin. The results will decide the makeup of the Assembly for the next four years, and they could also determine the political fate of the two rival leaders.The opposition leader Lee Jae-myung, top left, with a Democratic Party candidate for Parliament, Park Seong-joon, at a rally in Seoul on Saturday.Lee Jin-Man/Associated PressIf his party suffers a major loss, Mr. Yoon, 63, could essentially become a lame duck for the rest of his single, five-year term and could even face the threat of impeachment. Mr. Lee, 59, who has faced bribery and other criminal charges in court, is equally desperate to score an electoral victory.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    A K-Pop Star’s Lonely Downward Spiral

    Goo Hara’s life was a struggle from the start. She ended it at 28, isolated and harassed online.The K-pop star looked utterly drained. Her face scrubbed of makeup, Goo Hara, one of South Korea’s most popular musical artists, gazed into the camera during an Instagram livestream from a hotel room in Japan. In a fading voice, she read questions from fans watching from around the world.“You going to work, fighting?” one asked.In halting English, she gave a plaintive answer: “My life is always so fighting.”By the time she climbed into bed at the end of the livestream in November 2019, she had reached a low point after a lifetime of struggle. As a child, she was abandoned by her parents. Her father at one point attempted suicide. After grueling training, she debuted in a K-pop group at 17, early even by the standards of the Korean hit-making machine.With the group, Kara, she found international fame, and Ms. Goo became a regular on Korean television, eventually anchoring her own reality series. But with celebrity came ravenous attacks on social media from a Korean public that is as quick to criticize stars as it is to fawn over them. Following a sordid legal fight with an ex-boyfriend, the harassment only intensified, as commenters criticized her looks, her personality and her sex life.Ms. Goo in 2018, the year before she died by suicide.Choi Soo-Young/Imazins, via Getty ImagesOn Nov. 23, 2019, less than a week after her Instagram appearance, she posted a photo of herself tucked in bed, with the caption “Good night.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Why South Korean Doctors Have Walked Off the Job

    Physicians say the government’s plan to admit more students to medical school ignores the real cause of doctor shortages: harsh conditions and low wages.Hundreds of interns and residents in South Korea walked off the job on Tuesday, disrupting an essential service to protest the government’s plan to address a shortage of doctors by admitting more students to medical school.While South Korea takes pride in its affordable health care system, it has among the fewest physicians per capita in the developed world. Its rapidly aging population underscores the acute need for more doctors, according to the government, especially in rural parts of the country and in areas like emergency medicine.The protesters, who are doctors in training and crucial for keeping hospitals running, say the shortage of doctors is not industrywide but confined to particular specialties, like emergency care. They say the government is ignoring the issues that have made working in those areas unappealing: harsh working conditions and low wages for interns and residents.Surveys have found that in a given week, doctors in training regularly work multiple shifts that last longer than 24 hours, and that many are on the job for more than 80 hours a week.“The medical system has been collapsing for a while,” said Park Dan, the head of the Korean Intern Residents Association, who resigned from his job at the emergency wing of Severance Hospital in Seoul on Monday. “I couldn’t see a future for myself working in emergency for the next five or 10 years.”The current setup of insurance and government payment systems, Mr. Park added, allows physicians only in a few departments, like cosmetic surgery, to make a decent living.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Is North Korea Planning a War?

    An intensification of nuclear threats from North Korea while the world is preoccupied with other wars has ignited an urgent debate over Mr. Kim’s motives.North Korea fired hundreds of artillery shells in waters near South Korean border islands on Jan. 5. Last week, it said it no longer regarded the South as inhabited by “fellow countrymen” but as a “hostile state” it would subjugate through a nuclear war. On Friday, it said it had tested an underwater nuclear drone to help repel U.S. Navy fleets.That new drumbeat of threats, while the United States and its allies have been preoccupied with the wars in Ukraine and the Middle East, has set foreign officials and analysts wondering whether the North’s leader, Kim Jong-un, has moved beyond posturing and is planning to assert more military force.For decades, a central part of the North Korean playbook has been to stage carefully measured and timed military provocations — some aimed at tightening internal discipline, others at demanding attention from its neighbors and the United States, or all of that at once.But to several close watchers of North Korea, the latest round of signals from Mr. Kim feels different. Some are taking it as a clue that the North has become disillusioned with seeking diplomatic engagement with the West, and a few are raising the possibility that the country could be planning a sudden assault on South Korea.A New Year’s celebration in Pyongyang, North Korea’s capital, on Dec. 31, 2023.Kim Won Jin/Agence France-Presse — Getty ImagesTwo veteran analysts of North Korea — the former State Department official Robert L. Carlin and the nuclear scientist Siegfried S. Hecker — sounded an alarm this past week in an article for the U.S.-based website 38 North, asserting that Mr. Kim was done with mere threats. “Kim Jong-un has made a strategic decision to go to war,” they wrote.Analysts broadly agree that North Korea has been shifting its posture in recent years, compelled by an accumulation of both internal problems, including a moribund economy and food and oil shortages, and frustrations in its external diplomacy, like Mr. Kim’s failure to win an end to international sanctions through direct diplomacy with President Donald J. Trump. And most agree that the North’s recent closeness with Russia, including supplying artillery shells and missiles for use in Russia’s war in Ukraine, will be a game-changer in some way.But there is still stark disagreement over where Mr. Kim’s new tack might be leading.Many say that Mr. Kim’s ultimate goal remains not a war with South Korea, a treaty ally of the United States, but Washington’s acceptance of his country as a nuclear power by prompting arms-reduction talks.“The North Koreans won’t start a war unless they decide to become suicidal; they know too well that they cannot win the war,” said Park Won-gon, a North Korea expert at Ewha Womans University in Seoul. “But they would love their enemies to believe that they could, because that could lead to engagement and possible concessions, like the easing of sanctions.”Posters in Pyongyang remind citizens of North Korea’s need to remain on a war footing.Cha Song Ho/Associated PressAnalysts in China, North Korea’s most vital ally, were also deeply skeptical that Mr. Kim would go to war unless the North were attacked. Prof. Shi Yinhong, at Renmin University in Beijing, asserted that the North’s leadership, not being irrational, ultimately acted out of self-preservation — and that starting a war would work against that goal.Others noted that the North could assert itself militarily, including through smaller conventional strikes and bolder weapons testing, without necessarily triggering a deadly response.“There are many rungs of the escalation ladder that North Korea can climb short of all-out war,” said Victor Cha, a Korea expert at the Washington-based Center for Strategic and International Studies. “Kim is not that confident in his capabilities to deter U.S. reaction if he were to do something rash.”If Mr. Kim wants to climb that ladder, recent history suggests that this might be the time.North Korea has liked to unsettle its enemies at their most sensitive political moments, and both the United States and South Korea are holding elections this year. The North launched a long-range rocket in late 2012, between the United States and South Korean presidential elections. It conducted a nuclear test shortly before the inauguration of a South Korean leader in 2013. In 2016, it conducted another nuclear test two months before the American presidential election.North Korea could also attempt provocations in the coming weeks to try to help liberals who favor inter-Korean negotiations win parliamentary elections in South Korea in April, said the analyst Ko Jae-hong at the Seoul-based Institute for National Security Strategy. Through provocations, North Korea hopes to spread fears among South Korean voters that increasing pressure on the North, as the current administration of President Yoon Suk Yeol has tried to do, might “lead to a nuclear war,” he said.South Korean military exercises this month near the border with North Korea.Ahn Young-Joon/Associated PressNorth Korea “will continue to increase tensions until after the U.S. elections,” said Thomas Schäfer, a former German diplomat who served twice as ambassador to North Korea. But “at the height of tensions, it will finally be willing to re-engage with a Republican administration in the hope to get sanctions relief, some sort of acceptance of their nuclear program, and — as main objective — a reduction or even complete withdrawal of U.S. troops from the Korean Peninsula,” Mr. Schäfer said in a rebuttal to Mr. Carlin’s and Mr. Hecker’s analysis.Since Mr. Kim came to power in 2011, he has committed to building North Korea’s nuclear capability, using it both as a deterrent and as a negotiating tool to try to win concessions from Washington, like the removal of U.N. sanctions, to achieve economic growth.He tried it when he met Mr. Trump in 2018 and again in 2019. It failed spectacularly, and Mr. Kim returned home empty-handed and in humiliation.President Donald J. Trump and Kim Jung-un in 2019 in the Demilitarized Zone. In talks that year, the two failed to reach a deal on North Korea abandoning its nuclear ambitions in return for concessionsErin Schaff/The New York TimesHe then vowed to find a “new way” for his country.Since then, the North has rejected repeated calls from Washington for talks. It has also rejected South Korea as a dialogue partner, indicating from 2022 that it would use nuclear weapons against South Korea in a war and abandoning its long-held insistence that the weapons would keep the Korean Peninsula peaceful as a deterrent. It has tested more diverse, and harder-to-intercept, means of delivering its nuclear warheads.There is doubt that the North has yet built a reliable intercontinental ballistic missile that could target the United States. But two of the North’s main enemies, South Korea and Japan, are much closer.On the diplomatic front, Mr. Kim has taken pains to signal that he no longer views the United States as a critical negotiating partner, instead envisioning a “neo-Cold War” in which the United States is in retreat globally. He has aggressively improved military ties with Russia, and in return has most likely secured Russian promises of food aid and technological help for his weapons programs, officials say.South Korean troops patrol the entrance to a beach on an island near the sea boundary with North Korea.Jung Yeon-Je/Agence France-Presse — Getty Images“I worry that his confidence might lead him to misjudge with a small act, regardless of his intention, escalating to war amid a tense ‘power-for-power’ confrontation with the United States and its allies,” said Koh Yu-hwan, a former head of the Korea Institute for National Unification in Seoul.Despite its own increasingly aggressive military posture in recent years, China may prove to be a damper on any North Korean military adventurism.China and North Korea are bound by a treaty signed in 1961 that requires each country to provide military assistance if the other is attacked. But China has little incentive to be drawn into a war in Korea right now.“A war on the Korean Peninsula would be disastrous for Beijing. An entire half-century of peace in East Asia, a period of unprecedented growth for the P.R.C., would come to a crashing halt,” said John Delury, a professor of Chinese studies at Yonsei University in Seoul, referring to the People’s Republic of China.The United States has long leaned on Beijing to rein in North Korea. By drawing close to Moscow, Mr. Kim has been putting his own pressure on China’s leader, Xi Jinping.“It is notable that Kim made his first post-pandemic trip to the Russian Far East, skipping China, and he just sent his foreign minister to Moscow, not Beijing,” Mr. Delury said. By raising tensions, Mr. Kim “can see what Xi is willing to do to placate him,” he added.David Pierson More

    Attack on Opposition Leader Raises Alarms in Divided South Korea

    The attack on Lee Jae-myung, who narrowly lost the 2022 presidential vote, came amid a deepening political divide and increasingly extreme discourse in South Korea.Lee Jae-myung, South Korea’s opposition party leader, was attacked by a man who wearing a blue paper crown. In footage from Korean media, the attacker’s image has been blurred.@barunsori/YouTube via ReutersThe man accused of stabbing Lee Jae-myung, the leader of South Korea’s main opposition party, in the neck had been stalking him in recent weeks, including attending a political event where Mr. Lee was present on Dec. 13, apparently captured on video there wearing a blue paper crown, the police say.At a rally on Tuesday, a man wearing a similar paper crown and carrying a message supporting Mr. Lee and his party was also carrying something else: a knife with a five-inch blade and a plastic handle wrapped with duct tape.The attack, the worst against a South Korean politician in nearly two decades, seriously wounded Mr. Lee, who officials said was recovering in an intensive care unit at Seoul National University on Wednesday after surgery. And it deeply shocked a country that values hard-won years of relative peace after an era of political and military violence before establishing democracy in the 1990s.The opposition leader Lee Jae-myung after being attacked in Busan, South Korea, on Tuesday. Officials said he was recovering in Seoul after surgery.Yonhap, via ReutersThe police said that the suspect, a 66-year-old real estate agent named Kim Jin-seong, had admitted an intent to kill Mr. Lee. Armed with a court-issued warrant, the police confiscated Mr. Kim’s mobile phone and raided his home and office in Asan, south of Seoul, on Wednesday, as they tried to piece together what might have motivated that attack.With details still scarce, public debate and news editorials were expressing a growing concern about South Korea’s deepening political polarization and the hatred and extremism it has seemed to inspire, as well as the challenges it posed to the country’s young democracy.“The opposition leader falls under a knife of ‘politics of hatred,’” read a headline from the Chosun Ilbo, the country’s leading conservative daily.Officials said that little was known about Mr. Kim’s personal life or political and other background except that he was a former government official who had been operating a real estate agency in Asan since 2012. Police found no previous records of crime, drug use or psychiatric trouble, and said he was sober at the time of the attack on Mr. Lee. His neighbors said they had little interaction with him.One neighbor remembered him as a kind and hard-working “gentleman” who kept his office open every day, even on weekends, but who didn’t speak with him about politics and lived alone in an apartment.“He’s not someone who’d do such a thing,” said Park Min-joon, who runs a building management company. “I couldn’t believe it.”Investigators from the Busan Metropolitan Police Agency on Wednesday raiding the office of the suspect in the attack.Yonhap/EPA, via ShutterstockThe deep and bitter rivalry between Mr. Lee and President Yoon Suk Yeol has been center stage in South Korea’s political polarization since 2022, when Mr. Lee lost to Mr. Yoon with the thinnest margin of any free presidential election in South Korea. Instead of retiring from politics, as some presidential candidates have after defeats, Mr. Lee ran for — and won — a parliamentary seat, as well as chairmanship of the opposition Democratic Party.Under Mr. Yoon, state prosecutors have launched a series of investigations against Mr. Lee and tried to arrest him on various corruption and other criminal charges. Mr. Yoon has also refused to grant Mr. Lee one-on-one meetings that South Korean presidents had often offered opposition leaders to seek political compromises. Instead, he has repeatedly characterized his political opponents as “anti-state forces” or “corrupt cartels.”For his part, Mr. Lee accused Mr. Yoon of deploying state law-enforcement forces to intimidate his enemies. His party has refused to endorse many of Mr. Yoon’s appointees to the Cabinet and the Supreme Court. Political commentators likened the relationship between Mr. Yoon and Mr. Lee to “gladiators’ politics.”“The two have been on a collision course for two years,” said Park Sung-min, head of MIN Consulting, a political consultancy. “President Yoon has been accused of not recognizing Lee Jae-myung as an opposition leader but rather as a criminal suspect. I don’t think his attitude will likely change following the knife attack against Lee.”The last major attack on a domestic political leader happened in 2006, when Park Geun-hye, then an opposition leader, was slashed in the face with a box cutter. But the attack was seen largely as an isolated outburst of anger by an ex-convict who complained of mistreatment by the law enforcement system. (Ms. Park went on to win the 2012 presidential election.)Park Geun-hye, chairwoman of the Grand National Party, was attacked by a man with a box cutter during a campaign for local elections in Seoul in 2006. In 2012, she won the presidential election.Cbs Nocutnews, via Associated PressBut in recent years, politicians have been increasingly exposed to hatred in the public sphere, as political polarization deepened. In a survey sponsored by the newspaper Hankyoreh in December, more than 50 percent of respondents said they felt the political divide worsening. In another survey in December, commissioned by the Chosun Ilbo, four out of every 10 respondents said they found it uncomfortable to share meals or drinks with people who didn’t share their political views.South Koreans had an early inkling of the current problem. During the presidential election campaign in 2022, Song Young-gil, an opposition leader, was attacked by a bludgeon-wielding man in his 70s, who subsequently killed himself in jail.Jin Jeong-hwa, a YouTuber whose channel openly supports Mr. Lee and who live-streamed the knife attack on Tuesday, said he could feel the increasing political tension and hatred everyday. Once, when he visited a conservative town in central South Korea, people who recognized him tried to chase him out, threatening him with knives and sickles.“You see a lot of anger, vilification, character assassination and demonizing,” Mr. Jin said. “I am not sure whether rational debate on issues and ideologies is possible anymore.”Rep. Kwon Chil-seung, center, a senior spokesman for the opposition Democratic Party, gives an update on Mr. Lee’s condition in Seoul on Wednesday.Yonhap/EPA, via ShutterstockOn Wednesday, Mr. Yoon wished Mr. Lee a quick recovery, calling attacks against politicians “an enemy of free democracy.” His government ordered beefed-up public security for politicians.But analysts saw little chance of political polarization easing anytime soon as the rival parties geared up for parliamentary elections in April. Social media, especially YouTube, has become so influential as a channel of spreading news and shaping public opinion that politicians said they found themselves beholden to populist demands from activist YouTubers who were widely accused of stoking fear and hatred.Both Mr. Yoon and Mr. Lee have fervent online supporters who often resort to whipping up insults, conspiracy theories and even thinly veiled death threats against their foes.“Hate has become a daily norm” in South Korean politics, said Mr. Park, the head of MIN Consulting. “Politicians must face the reality that similar things can happen again,” he said, referring to the knife attack against Mr. Lee.

    The Camp David summit signals a new cold war – this time with China | Observer editorial

    If it sounds like a new cold war and looks like a new cold war, then it probably is a new cold war. For what other interpretation is to be placed on US president Joe Biden’s latest ramping up of diplomatic, economic and military pressure on China?Western officials tend to avoid the term, recalling as it does decades of hair-trigger confrontation with the former Soviet Union. They talk instead about enhanced security and defence cooperation and the importance of a free and open Indo-Pacific region. But such bland generalisations belie the fact that Biden is now pushing back hard at a repressive, authoritarian regime in Beijing that he and many Americans believe is determined to overthrow the international democratic, geopolitical and legal order safeguarded by the US. Last week’s groundbreaking Camp David summit hosted by Biden for Japan’s prime minister, Fumio Kishida, and South Korea’s president, Yoon Suk Yeol, perfectly fitted this agenda. It produced a series of measures aimed squarely at China and its “dangerous and aggressive behaviour”.They include a trilateral mechanism to deal with perceived security threats; expanded military exercises; and increased ballistic missile cooperation – despite the risk that China could retaliate in like fashion or use economic sanctions, as in the past, to punish export-dependent Tokyo and Seoul.For Japan, the Camp David agreement marks another significant stage in its journey away from postwar pacifism towards becoming a fully fledged, fully armed member of the US-led western democratic alliance. It will add to Tokyo’s sense of growing confrontation with China.For South Korea, the trilateral pact may come to be seen as the moment it finally moved on from the bitter feud with Japan over the latter’s 20th-century colonisation of the peninsula. Credit is due to Yoon, who has taken to describing Tokyo as a “partner” with shared values and interests.Biden’s success in bringing old enemies together is a notable achievement, too. He is hoping to pull off a similar feat with Israel and Saudi Arabia. The contrast with Donald Trump’s fatuous attempts to woo Kim Jong-un, North Korea’s nuclear-armed dictator, is striking.Improved three-way cooperation in facing down the threat posed by Pyongyang may be another benefit of Camp David. Defying UN sanctions, Kim has stepped up his intimidatory missile “tests” this year. China, disappointingly, has done little to stop him. Beijing’s ally, Russia’s Vladimir Putin, is positively encouraging him.While US officials are careful how they frame the new agreement, China is in no doubt it is aimed directly at itself. It follows Biden’s upgrading of the so-called Quad, which groups the US, India, Japan and Australia; the creation of Aukus, a security pact with Australia and the UK; and a raised US naval and air force profile in the Philippines, South China Sea and around Taiwan. In another message to Beijing, Biden will visit India next month.The numerous, ill-judged actions of President Xi Jinping’s regime have brought much of this down on its own head. Nevertheless, Beijing blames the west whose nefarious aim, it says, is containment designed to stifle China’s development. State media described Camp David as the launch of a “mini Nato” that will threaten regional security and exacerbate tensions.US officials reject the analogy. But the claim brings us back to the question of a new cold war. China evidently believes one has already begun. Is this really what Biden, the UK and regional allies want? If that is the case, they should have the courage to say so in terms – and explain what they plan to do if it turns “hot”. More

    U.S. Seals Security Pact With Japan and South Korea as Threats Loom

    While the former president’s name appeared nowhere in the communique issued by three leaders, one of the subtexts was the possibility that he could return to power in next year’s election and disrupt ties with America’s two closest allies in the Indo-Pacific region.The new three-way security pact sealed by President Biden and the leaders of Japan and South Korea at Camp David on Friday was forged with threats by China and North Korea in mind. But there was one other possible factor driving the diplomatic breakthrough: Donald J. Trump.While the former president’s name appeared nowhere in the “Camp David Principles” that the leaders issued at the presidential retreat, one of the subtexts was the possibility that he could return to power in next year’s election and disrupt ties with America’s two closest allies in the Indo-Pacific region.Both Japan and South Korea struggled for four years as Mr. Trump threatened to scale back longstanding U.S. security and economic commitments while wooing China, North Korea and Russia. In formalizing a three-way alliance that had long eluded the United States, Mr. Biden and his counterparts hoped to lock in a strategic architecture that will endure regardless of who is in the White House next.“This is not about a day, a week or month,” Mr. Biden said at a joint news conference with Prime Minister Fumio Kishida of Japan and President Yoon Suk Yeol of South Korea. “This is about decades and decades of relationships that we’re building.” The goal, he added, was to “lay in place a long-term structure for a relationship that will last.”Asked by a reporter why Asia should be confident about American assurances given Mr. Trump’s campaign to recapture the presidency on a so-called America First platform, Mr. Biden offered a testimonial to the value of alliances in guaranteeing the nation’s security in dangerous times.“There’s not much, if anything, I agree on with my predecessor on foreign policy,” Mr. Biden said, adding that “walking away from the rest of the world leaves us weaker, not stronger. America is strong with our allies and our alliances and that’s why we will endure.”The meeting at the getaway in the Catoctin Mountains of Maryland was a milestone in Mr. Biden’s efforts to stitch together a network of partnerships to counter Chinese aggression in the region. While the United States has long been close to Japan and South Korea individually, the two Asian powers have nursed generations of grievances that kept them at a distance from one another.The alignment at Camp David was made possible by Mr. Yoon’s decision to try to put the past behind the two countries. His rapprochement with Tokyo has not been universally popular at home with a public that harbors long memories of the Japanese occupation in the first half of the 20th century, but both sides made clear they are dedicated to a fresh start.“That’s a long, bitter colonial wound that President Yoon has to jump over, and Kishida as well,” said Orville Schell, director of the Center on U.S.-China Relations at the Asia Society. “That I think is a consonant expression of the degree to which China’s rather belligerent, punitive behavior has driven together allies, partners and friends within Asia.”Mr. Biden hoped to capitalize on that by bringing the Japanese and South Korean leaders together for the first stand-alone meeting between the three nations that was not on the sidelines of a larger international summit. He repeatedly praised Mr. Yoon and Mr. Kishida for “the political courage” they were demonstrating.He chose the resonant setting of Camp David for the talks to emphasize the importance he attaches to the initiative, inviting the leaders to the storied retreat that has been the site of momentous events over the decades, including most memorably Jimmy Carter’s 13-day negotiation in 1978 brokering peace between Israel and Egypt.“This is a big deal,” Mr. Biden said, noting that it was the first time he had invited foreign leaders to the camp since taking office. “This is a historic meeting.”The others echoed the sentiments. “Today will be remembered as a historic day,” Mr. Yoon said. Mr. Kishida agreed, saying the fact that the three could get together “means that we are indeed making a new history as of today.”A stronger collaboration with Japan and South Korea could be a significant pillar in Mr. Biden’s strategy to counter China.Samuel Corum for The New York TimesThe leaders agreed to establish a three-way hotline for crisis communications, enhance ballistic missile cooperation and expand joint military exercises. They issued a written “commitment to consult” in which they resolved “to coordinate our responses to regional challenges, provocations, and threats affecting our collective interests and security.”The commitment is not as far-reaching as NATO’s mutual security pact, which deems an attack on one member to be an attack on all, nor does it go as far as the defense treaties that the United States has separately with Japan and South Korea. But it cements the idea that the three powers share a special bond and expect to coordinate strategies where possible.China has derided the idea of a “mini-NATO” in Asia, accusing Washington of being provocative, but aides to Mr. Biden stressed the difference from the Atlantic alliance. “It’s explicitly not a NATO for the Pacific,” said Jake Sullivan, the national security adviser.Mr. Biden and his aides maintained that the collaboration sealed at Camp David should not be seen as aimed at China or any other country. “This summit was not about China. This was not the purpose,” the president said. “But obviously China came up.” Instead, he said, “this summit was really about our relationship with each other and defining cooperation across an entire range of issues.”Still, no one had any doubt about the context against which the meeting was taking place. The Camp David Principles issued by the leaders did not directly mention China, but it did “reaffirm the importance of peace and stability across the Taiwan Strait,” a warning against aggressive military actions by Beijing.The documents released were more explicit about nuclear-armed North Korea and the joint efforts they will take to counter its military, cyber and cryptocurrency money laundering threats.Looming in the backdrop was Mr. Trump, whose mercurial actions and bursts of hostility while president flummoxed Japanese and South Korean leaders accustomed to more stable interactions with Washington.At various points, he threatened to withdraw from the U.S. defense treaty with Japan and to pull all American troops out of South Korea. He abruptly canceled joint military exercises with South Korea at the request of North Korea and told interviewers after leaving office that if he had a second term he would force Seoul to pay billions of dollars to maintain the United States military presence.The summit at Camp David was aimed at ending decades of friction between the two Asian countries.Samuel Corum for The New York TimesThe Asian leaders hope that the three-way accord fashioned by Mr. Biden will help avoid wild swings in the future. The president and his guests sought to institutionalize their new collaboration by committing to annual three-way meetings in the future by whoever holds their offices.“There’s definitely risk-hedging when it comes to political leadership,” said Shihoko Goto, acting director of the Asia program at the Woodrow Wilson International Center for Scholars.”By deepening the cooperation below the leader level through various new mechanisms, she said, the governments may be able to maintain functional ties even if a volatile president occupies the White House.“If a new U.S. president were to avoid going to international conferences or had no interest in engaging, the trilateral institutionalization of ties should be strong enough so that working relations between the three countries would continue,” she said. “So it won’t matter if a president didn’t show up since the working-level military or economic cooperation would be well-established.”It is not the first time allies have questioned the United States’ commitment to its partners. Despite Mr. Biden’s promise at the NATO summit last month that Washington would “not waver” in its support for Ukraine and western allies, some leaders openly asked whether the U.S. foreign policy agenda would be upended by the outcome of the next election.Ukraine needed to make military progress more or less “by the end of this year” because of the coming elections in the United States, President Petr Pavel of the Czech Republic warned on the first day of the summit.Mr. Biden in Finland was also asked about whether the U.S. support of NATO would endure. “No one can guarantee the future, but this is the best bet anyone could make,” Mr. Biden said then.At Camp David on Friday, neither Mr. Yoon nor Mr. Kishida mentioned Mr. Trump directly in their public comments, but they seemed intent on ensuring that their agreement persists beyond their tenures. Mr. Yoon said the nations were focused on building an alliance that could last for years to come. The three nations will hold a “global leadership youth summit to strengthen ties between our future generations,” he said.Endurance was a running theme throughout the day. “We’re opening a new era,” Mr. Sullivan told reporters shortly before the meetings opened, “and we’re making sure that era has staying power.”Ana Swanson More
