US Navy patrols Taiwan Strait before Xi-Trump summit, triggering PLA manoeuvres

The United States Navy executed a strategic transit of the Taiwan Strait on March 12, 2026, deploying a P-8A Poseidon maritime patrol aircraft through the international airspace of the critical waterway. The US Seventh Fleet publicly announced the mission, with spokesman Commander Matthew Comer framing it as a demonstration of the US commitment to a 'free and open Indo-Pacific.' This marked the first publicly acknowledged US military transit of the strait this year, though such operations are conducted routinely. The timing is highly significant, occurring just weeks before a planned summit between US President Donald Trump and Chinese President Xi Jinping, scheduled for March 31 to April 2, where Taiwan is expected to be a key agenda item.

Beijing responded swiftly to the US patrol. The flight triggered immediate manoeuvres by People's Liberation Army (PLA) fighter jets near Taiwan, ending a brief pause in such activity. China views Taiwan as a breakaway province that must be reunified, by force if necessary. While the US officially adheres to the 'One China' policy and does not recognize Taiwan as a sovereign state, it maintains a policy of supplying the island with defensive weapons and opposes any unilateral change to the status quo by force. This naval patrol serves as a tangible, public signal of that commitment amidst high-stakes diplomatic preparations, underscoring the persistent military dimension of cross-strait tensions.
