China’s leader Xi Jinping started a week of diplomacy in Southeast Asia with a visit to Vietnam, signaling China’s commitment to global trade.

China’s leader is on a charm offensive in the region, but some of Beijing’s neighbors are wary of being caught in the crossfire of a superpower rivalry.

In the aftermath of the strike, Volodymyr Zelenskiy called on the U.S. and Europe to get tough on Russia in response to what he described as terrorism.
