On day two of an unannounced visit to Taiwan, a U.S. delegation of lawmakers and military officials toured the island’s technology hub in Hsinchu, according to local media. Taiwan and U.S. officials have remained tight-lipped on the details of the visit ever since the delegation arrived on a military aircraft late on Tuesday. But Beijing has said it could undermine the U.S.-China relationship ahead of a rare meeting between leaders Xi Jinping and Joe Biden. Rik Glauert reports.
