China Sends Warplanes Over Taiwan as US Envoy Visits John Xie China sent almost 20 warplanes into Taiwan's airspace in an unusually large show of force as a response to a senior U.S. official's visit to the self-governing island. Eighteen Chinese military aircraft, including two H-6 strategic bombers and fighter jets, crossed the so-called median line on Friday morning, according to a statement from Taiwan's defense ministry: "The military scrambled fighters and deployed air defense missile systems to monitor the activities." Keith Krach, U.S. undersecretary for economic affairs, arrived in Taiwan on Thursday to attend a memorial service for former President Lee Teng-hui. He is the highest-level official from the U.S. State Department to visit Taipei in decades. .
