In May 2022, Joe Biden was on a charm offensive. The US president invited the leaders of 10 Southeast Asian nations to the White House for the first time for talks about the region, which is home to more than 600 million people. High on the agenda was China—a key trading partner for all the countries, but also a potential threat to their stability. Biden promised $150 million in extra support for the nations to help improve their security, infrastructure, and ongoing pandemic response.
