A U.S. Navy surveillance plane made its way through the Taiwan Strait on Friday, marking the first time in five months that such an event has been publicly noted. This occurrence comes just before Chinese President Xi Jinping’s anticipated trip to Washington in September.
The P-8A Poseidon aircraft traveled from the East China Sea into the South China Sea, navigating through international airspace in what the Navy termed a routine transit, according to a report from U.S. 7th Fleet spokesman Cmdr. Matthew Comer. This flight is the first publicly reported Navy P-8 journey through the approximately 110-mile-wide strait since March 11.
While Beijing asserts that Taiwan is its territory and claims authority over the strait, both the U.S. and Taiwan view the strait as an international waterway.
“By operating within the Taiwan Strait in accordance with international law, the United States reinforces the navigational rights of all nations,” Comer told the Daily Caller News Foundation. He added that the flight shows the U.S.’s commitment to a free and open Indo-Pacific, emphasizing that the military operates wherever international law permits.
The Pentagon didn’t provide any comments when asked about the flight.
A U.S. Navy P-8A Poseidon maritime patrol aircraft transited the Taiwan Strait on Aug. 21, flying along the western side of the Strait median line before turning south through southwestern Taiwan toward the Bashi Channel.

The P-8A is designed for various maritime missions, including anti-submarine warfare and reconnaissance, as explained by a report from the Naval Air Systems Command. It is equipped with technologies such as synthetic aperture radar and infrared sensors, which aid in maritime detection and tracking.
According to Zack Cooper, a senior fellow at the American Enterprise Institute, the flight is a routine operation. He noted that it’s positive they are continuing this amidst a seeming pause in some actions related to Taiwan leading up to the upcoming Xi-Trump summit next month.
U.S. naval vessels frequently pass through the Taiwan Strait, though public flights by military aircraft, like that of the P-8, happen less often. Previous P-8 missions have been characterized by the Navy as actions taken in line with international law, showcasing U.S. support for navigational rights.
During the P-8’s flight on Friday, China’s military monitored its passage, as reported by the Chinese state-run Global Times. They mentioned that the situation remained “under control,” according to a Chinese military source.
Chinese media referred to the U.S. mission as “close-in reconnaissance,” implying it exuded some “element of military pressure.” This is a typical reaction, as Beijing regularly objects to U.S. military operations in the strait, asserting sovereignty while Washington and Taipei reject these claims.
This flight takes place just ahead of an important meeting between Trump and Xi, with the Chinese leader likely visiting the U.S. on September 24, as stated by Trump. Both Secretary of State Marco Rubio and Chinese Foreign Minister Wang Yi have also engaged in discussions as the two sides prepare for Xi’s visit.
The Taiwan issue continues to be a significant point of tension between Washington and Beijing, especially as they strive to stabilize relationships challenged by Taiwan, trade disagreements, and technology constraints.
