Chinese state media reported that Xi Jinping raised the question of Taiwan during his meeting with Donald Trump. The pair held talks for about two hours, DW reports.
“The Taiwan question is the most important issue in China-US relations,” Xi said, according to state broadcaster CCTV.
“If mishandled, the two nations could collide or even come into conflict, pushing the entire China-US relationship into a highly perilous situation.”
China also restated on Wednesday its opposition to a recent US weapons deal with Taiwan.
China claims self-governed Taiwan as part of its territory and says it must be “reunified” with the mainland.
