China vowed reprisals against Taiwan after a meeting between the United States House speaker and the island’s president, saying Thursday that the U.S. was on a “wrong and dangerous road.” Speaker Kevin McCarthy hosted Taiwan President Tsai Ing-wen on Wednesday in a show of U.S. support for the self-ruled island, which China claims as its own, along with a bipartisan delegation of more than a dozen U.S. lawmakers.

The Biden administration maintains there is nothing provocative about the visit by Tsai, which is the latest of a half-dozen to the U.S. Yet, it comes as the U.S.-China relationship has fallen to historic lows, with U.S. support for Taiwan becoming one of the main points of difference between the two powers.
