TAIPEI, Taiwan (AP) — U.S. House Speaker Nancy Pelosi has arrived in Taiwan. She is the highest-ranking American official in 25 years to visit the self-ruled island claimed by China, which quickly announced that it would conduct military maneuvers in retaliation for her presence. Pelosi arrived aboard a U.S. Air Force passenger jet and was greeted on the tarmac at Taipei’s international airport by Taiwan’s foreign minister and other Taiwanese and American officials. She posed for photos before her motorcade whisked her unseen into the parking garage of her hotel. Her visit has ratcheted up tension between China and the United States.
