On May 10, a Chinese WZ-10 attack helicopter made headlines for crossing the centerline of the Taiwan Strait. This centerline incursion was the first to occur since September 2020, when then-Under Secretary of State for Economic Growth, Energy, and the Environment Keith Krach visited Taipei to attend the funeral of Taiwanese President Lee Teng-hui (李登輝) and to discuss the launch of the US-Taiwan Economic Prosperity Partnership Dialogue (EPPD). During the September 2020 incursion, close to 40 aircraft crossed the centerline while conducting a live-fire drill. That provocation was promptly condemned by the United States, and no Chinese military aircraft crossed the centerline afterwards—until May 2022. During the latest incident, two KA-28 anti-submarine warfare (ASW) helicopters also flew into Taiwan’s southwestern air defense identification zone (ADIZ), which is the regular location for such incursions.

Centerline crossings, which are very uncommon, are considered a major form of escalation given the proximity to Taiwan.
