China warns of reprisal as Taiwan's president visits the US

Taiwan's President Tsai Ing-wen is on a multi-day trip to Central and North America, including stops in the United States, which China is closely watching. If Tsai meets House Speaker Kevin McCarthy, China would consider it a provocation that violates the one-China principle. Both Taipei and Washington are treading a careful line, with Tsai's U.S. stops being called transits and her office stressing she is stopping in the U.S. as a private individual. Tsai's trip comes at a tense moment for Taiwan, with Honduras recently switching ties to Beijing.
