US Speaker defies China warnings, meets with Taiwan's president.

China has warned US House Speaker Kevin McCarthy not to meet Taiwan President Tsai Ing-wen during her stopover in California, saying it would harm regional peace and stability and only unite the Chinese people behind a common enemy. McCarthy will host a meeting with Tsai, during a sensitive stopover in the US that has prompted Chinese threats of retaliation. China claims Taiwan as its own territory and staged war games around the island last August after then-Speaker Nancy Pelosi, a Democrat, visited the capital, Taipei.
