China’s Post‑Summit Military Pressure Around Taiwan, Explained

Taiwan’s MND publishes daily reports tracking People’s Liberation Army (PLA) aircraft and People’s Liberation Army Navy (PLAN) vessels operating around the island. These reports show continued activity during and after the summit.

May 14–15 (period ending 6 a.m. May 15)
Taiwan detected 7 PLAN ships and 1 Chinese official ship operating around the island. No PLA aircraft were recorded in that reporting window.

May 16–17 (period ending 6 a.m. May 17)
The MND reported 5 PLA aircraft sorties, 7 PLAN ships, and 1 official ship. Four of the five aircraft crossed the Taiwan Strait median line and entered Taiwan’s northern and southwestern ADIZ.

May 17–18 (period ending 6 a.m. May 18)
Taiwan detected 7 PLA aircraft sorties, 5 PLAN ships, and 1 official ship, with all seven aircraft crossing the median line and entering Taiwan’s northern and southwestern ADIZ.

May 18–19 (period ending 6 a.m. May 19)
Activity increased to 13 PLA aircraft sorties, 5 PLAN ships, and 2 official ships. Ten of the aircraft crossed the median line and entered Taiwan’s northern, southwestern, and eastern ADIZ sectors.

May 20–21 (period ending 6 a.m. May 21)
Taiwan recorded 7 PLA aircraft sorties, 7 PLAN ships, and 1 official ship, with six aircraft crossing the median line and entering the northern and southwestern ADIZ.

May 21–22 (period ending 6 a.m. May 22)
The following report listed 6 PLA aircraft sorties and 10 PLAN ships, and all six aircraft crossed the median line and entered Taiwan’s northern, southwestern, and eastern ADIZ.

Taken together, the reports show a pattern in which most detected aircraft crossed the median line on multiple days—an action that historically represented an unofficial buffer boundary in the Taiwan Strait.

Taiwan’s Military Response

In response to the incursions, Taiwan’s armed forces said they monitored the situation and deployed defensive assets. According to the MND, this included:

• Combat air patrol (CAP) aircraft
• Naval vessels
• Coastal missile systems

These assets were used to track and respond to Chinese aircraft and ships detected near the island.

ADIZ Incursions Before the Summit

The activity after the summit fits into a broader pattern seen earlier in May. For example:

• May 14 (period ending May 14): 3 PLA aircraft sorties and 6 PLAN ships were detected, with all three aircraft entering Taiwan’s southwestern and eastern ADIZ.
• May 11: 7 aircraft sorties and 5 PLAN ships were reported, with 5 aircraft crossing the median line and entering Taiwan’s ADIZ.
• May 2: Taiwan detected 29 PLA aircraft, 6 PLAN ships, and 2 official ships, including 15 aircraft crossing the median line and entering northern, central, and southwestern ADIZ sectors.

These earlier incidents show that Chinese military flights into Taiwan’s ADIZ and crossings of the median line were already occurring frequently prior to the summit.

Why the Pressure Continues

The military activity occurs amid ongoing geopolitical tensions surrounding Taiwan’s political status and security ties with the United States.

Beijing claims Taiwan as its territory and strongly opposes U.S. arms sales or military cooperation with the island. Those issues were part of the diplomatic backdrop to the Xi–Trump meeting in Beijing.

Taiwan’s leaders and officials have argued that China’s military actions—including aircraft incursions and naval deployments—constitute intimidation that undermines regional peace.

The Broader Pattern: Sustained Military Signaling

The reports from Taiwan’s MND illustrate what analysts increasingly describe as a persistent pressure campaign rather than a single escalation. Chinese aircraft sorties, median‑line crossings, and ADIZ incursions occur on many days, often accompanied by PLAN vessels operating nearby.

While the activity levels vary from day to day, the pattern reflects a sustained effort by Beijing to demonstrate military presence around Taiwan while signaling its opposition to Taiwan independence and to foreign military support for the island.

The days following the Xi–Trump summit therefore did not bring a pause in tensions. Instead, Taiwan’s official data shows the continuation of near‑daily Chinese military operations around the island, with repeated aircraft incursions and naval deployments reinforcing the broader strategic standoff in the Taiwan Strait.
