Increased Chinese Drone Patrols Near Taiwan and Philippine Sea

Through the spring of 2025 China stepped up flights of long-range military drones and crewed surveillance aircraft around Taiwan and out through the first island chain into the Philippine Sea, an escalation tracked publicly by both Taipei and Tokyo. USNI News reported in late April 2025 that People's Liberation Army uncrewed and reconnaissance aircraft had intensified patrols in the area, with Japan's air force intercepting eleven Chinese drones in the weeks after the Japanese fiscal year began on 01 April 2025.

The activity centred on the chokepoints of the first island chain. Imagery released by Japan's Joint Staff Office identified Chinese platforms including the TB-001 reconnaissance and strike drone, the BZK-005 long-endurance reconnaissance drone and the Wing Loong 2, repeatedly transiting the Miyako Strait between Okinawa and Miyako Island before turning south along Japan's southwestern islands and into the Pacific. The Bashi Channel between Taiwan and the Philippines was used on the same routes, letting aircraft fly the length of Taiwan's east coast.

The drone surge overlapped with the PLA's Strait Thunder-2025A exercise on 01 and 02 April 2025, a large drill around Taiwan and the Matsu Islands. Separately, The Diplomat reported that Japanese fighters scrambled against Chinese drones a record thirty times in fiscal 2024, a baseline the spring 2025 tempo built upon, with the Air Self-Defense Force's Southwestern Air Defense Command repeatedly launching interceptors.

The pattern fits sustained PLA grey-zone pressure rather than any single event. Long-range drones such as the TB-001 and BZK-005 let China map Taiwan's eastern approaches, probe Japanese and Taiwanese air defences and normalise a near-constant surveillance presence beyond the first island chain, all below the threshold of armed conflict. The repeated use of the Miyako Strait and Bashi Channel signals an intent to operate freely in the Philippine Sea, complicating any future allied response. The activity is openly attributable to the PLA; the buildup is best read as rehearsal and habituation, conditioning regional forces to a permanent Chinese military footprint.
