BALI, Indonesia — Prime Minister Hun Sen of Cambodia said on Tuesday that he had tested positive for Covid-19 and that his delegation would cut short its trip to Bali for the Group of 20 summit.
Mr. Hun Sen met with more than a dozen world leaders in the past three days, including President Biden, Prime Minister Justin Trudeau of Canada and Prime Minister Narendra Modi of India. All of them had flown to Phnom Penh, the capital of Cambodia, for the meeting of the Association of Southeast Asian Nations, which started Saturday.
The White House told reporters on Tuesday that Mr. Biden had tested negative that morning and was not considered a close contact, as defined by the Centers for Disease Control and Prevention.
In a Facebook post, Mr. Hun Sen wrote that before leaving Cambodia, he had been tested every day, including just before boarding his plane to Bali, an Indonesian island.
“It is lucky that I didn’t join the dinner that was organized by the French government with several heads of states last night, since I arrived late,” he said.
Mr. Hun Sen said the Cambodia delegation would return home Tuesday and that he would skip the Asia-Pacific Economic Cooperation summit in Bangkok later in the week, where he had been scheduled to meet with China’s top leader, Xi Jinping, and President Emmanuel Macron of France.
Mr. Hun Sen and Mr. Biden shook hands in Phnom Penh on Saturday. Neither was wearing a mask. They later had a meeting that lasted about half an hour. On Monday night, Mr. Biden coughed while speaking to reporters and told them that he had come down with a cold.
