Xi-Biden Apec summit: ex-US envoy Max Baucus calls for frank talks on Taiwan to ease ties. Ahead of the Apec summit, former US ambassador to China Max Baucus emphasized the need for candid discussions between US President Joe Biden and Chinese President Xi Jinping, particularly on the sensitive issue of Taiwan. Baucus highlighted the importance of the US understanding China's firm stance on Taiwan, suggesting non-confrontational clarity from Beijing could lead to more informed US policies. Tensions between the US and China have escalated over Taiwan, with the US stepping up arms sales and contacts with Taipei, actions that have been met with strong opposition from Beijing.
