The big questions hanging over the Trump-Xi meeting in China

US President Donald Trump is set to meet Chinese leader Xi Jinping in Beijing to discuss the US-China trade war, Taiwan, tariffs, and the Strait of Hormuz, but the meeting's agenda may be complicated by the US-Iran conflict. The meeting was initially postponed after Trump approved joint strikes with Israel against Iran. The US-China trade war and Middle East tensions are expected to be major topics of discussion.
