The competing strains on U.S. global power came into sharp focus at a security conference on Sunday, where China accused the United States of stoking tensions around Taiwan and the South China Sea, and President Volodymyr Zelensky of Ukraine was seeking greater support for his embattled country.<\/p>\n
These scenes played out at the Shangri-La Dialogue, an annual security forum in Singapore that has long been a barometer of the ups and downs of U.S.-China relations.<\/p>\n
This year, the United States Defense Secretary Lloyd J. Austin III and China\u2019s defense minister, Adm. Dong Jun, held talks<\/a>, something the top defense officials from the two countries have not always done at this gathering. But Admiral Dong made clear that China remained deeply antagonistic to U.S. influence and alliance-building across Asia, especially American support for Taiwan, the island democracy that Beijing claims as its territory.<\/p>\n \u201cThese malign intentions are drawing Taiwan to the dangers of war,\u201d Admiral Dong told the meeting after making an oblique but unmistakable reference to U.S. military and political support for Taiwan. \u201cAnyone who dares split Taiwan from China will be smashed to pieces and court their own destruction.\u201d<\/p>\n<\/div>\n<\/div>\n Admiral Dong\u2019s warnings, and other combative comments from Chinese military officers at the meeting, reflected how Beijing and Washington remain deeply divided over fundamental issues, even as they discuss ways to keep military friction at sea and in the air from spiraling into crisis.<\/p>\n<\/div>\n<\/div>\n Last month, China held two days of menacing military exercises<\/a> around Taiwan, accusing its new president, Lai Ching-te<\/a>, of trying to advance independence for the island. Mr. Lai has said he wants to preserve Taiwan\u2019s ambiguous status quo \u2014 self-ruled, yet short of full formal independence \u2014 but the Chinese officials describe him as a menace to Beijing\u2019s claims to the island.<\/p>\n \u201cI think that in essence it was a step toward Taiwan independence,\u201d Lt. Gen. He Lei, a former vice president of China\u2019s Academy of Military Sciences, said of Mr. Lai\u2019s inaugural speech last month. \u201cAs long as he goes further and further down the road of Taiwan independence, going deeper and deeper, the dangers in the Taiwan Strait will only increase.\u201d<\/p>\n Mr. Austin warned in a speech<\/a> on Saturday against \u201cactions in this region that erode the status quo and threaten peace and stability,\u201d an indirect reference to Chinese pressure on Taiwan. Mr. Austin also said \u201cwe all share an interest in ensuring that the South China Sea remains open and free,\u201d despite Chinese territorial claims across the sea.<\/p>\n<\/div>\n<\/div>\n But Admiral Dong accused an unnamed Southeast Asian country \u2014 clearly the Philippines \u2014 of stirring up trouble over disputed islands and shoals in the sea, and again suggested that the United States was the real culprit.<\/p>\n \u201cA certain country, incited by external forces, has abandoned bilateral agreements, broken its promises, and taken premeditated action to stir up incidents,\u201d he said in his speech to diplomats, military officials and experts, many from Asian countries. \u201cChina has exercised sufficient restraint in responding to these provocations, but this restraint has its limits.\u201d<\/p>\n<\/div>\n<\/div>\n The Philippines has been at odds with China over their rival claims in the South China Sea, in an area that Manila calls the West Philippine Sea. In 2016, an international tribunal under the United Nations Convention on the Law of the Sea rejected China\u2019s expansive claims in the South China Sea, which included shoals near the Philippines. Beijing ignored that ruling.<\/p>\n At the meeting in Singapore, the president of the Philippines, Ferdinand Marcos Jr., warned on Friday that his government could call on support from the United States under a mutual defense treaty in the event that a Chinese vessel caused the death of a Philippine sailor.<\/p>\n<\/div>\n<\/div>\n A U.S. official who heard Admiral Dong\u2019s speech took issue with his portrayal of China and its People\u2019s Liberation Army as the innocent victim in regional disputes. The official, speaking on condition of anonymity to discuss geopolitical tensions, said the admiral\u2019s assertion was at odds with the Chinese military\u2019s \u201ccoercive activity\u201d in the region.<\/p>\n Even in Singapore, Mr. Austin and other Western officials were also reminded that Ukraine\u2019s more than two-year war against Russian invasion continues to demand their leaders\u2019 attention and their taxpayers\u2019 resources.<\/p>\n Mr. Zelensky was a last-minute addition to the gathering. He met on Sunday with Mr. Austin, who provided an update on U.S. security assistance, according to a Pentagon readout of the meeting, before Mr. Zelensky addressed the conference. <\/p>\n<\/div>\n<\/div>\n He was greeted with loud applause before delivering a 15-minute speech promoting a peace summit on Ukraine in Switzerland next month that he said officials from 106 countries had agreed to join. He appealed to leaders across the Indo-Pacific to support the gathering with their attendance or ideas. <\/p>\n \u201cWe are ready to hear various proposals and thoughts that lead not to the continuation of the war \u2014 and this is very important \u2014 but to the end,\u201d he said. He added that only diplomacy with persistence would end the conflict. <\/p>\n \u201cThe world has to be resilient; it has to be strong; it has to put pressure on Russia,\u201d he told the gathering. \u201cThere is no other way to stop Putin.\u201d<\/p>\n Analysts said his appearance showed the increased interconnectedness among security issues worldwide. <\/span><\/p>\n \u201cIt\u2019s a reminder to countries in Asia and the Indo-Pacific that the war taking place in Ukraine isn\u2019t just a European problem. It\u2019s a problem for the world,\u201d said Bonnie S. Glaser, managing director of the Indo-Pacific program at the German Marshall Fund of the United States.<\/p>\n<\/div>\n<\/div>\n \u201cZelensky recognizes that he has to go out and remind the world to continue to support the fight that his country is engaged in,\u201d said Ms. Glaser, who was at the Singapore conference.<\/p>\n Mr. Zelensky said on social media<\/a> that he also had met with U.S. Congress members at the gathering in Singapore, including Representative Michael McCaul of Texas, a Republican who is the chairman of the House Foreign Affairs Committee. Mr. Zelensky thanked him for helping win approval<\/a> in April for additional military assistance for Ukraine, but also suggested more was needed.<\/p>\n \u201cWe talked about the frontline situation and military assistance, particularly additional systems and missiles to strengthen our air defense,\u201d Mr. Zelensky said.<\/p>\n<\/div>\n<\/div>\n
