Taiwanese President Tsai Ing-wen is set to meet U.S. House Speaker Kevin McCarthy on Wednesday in the first such meeting on U.S. soil, drawing threats of retaliation from China, which claims self-ruled Taiwan as its own. China staged war games around Taiwan last August following the visit to Taipei of then-House Speaker Nancy Pelosi and Taiwan’s defence ministry said a Chinese aircraft carrier group was in the waters off the island’s southeast coast ahead of the meeting between Tsai and McCarthy in California.
