China warns of confrontation as Taiwan's president visits US

Taiwan's President Tsai Ing-wen begins a visit to the United States and Central America to strengthen Taiwan's partnerships and show that the self-ruled island has allies as it faces a rising threat from China. China has warned against any official meetings between Tsai and senior US leaders, and pro-China demonstrators have rallied against her events in New York. Taiwan is an important partner for Washington in the Indo-Pacific and a major recipient of US military aid.
