Around once a month, US military ships or aircraft pass through or above the waterway that separates Taiwan from China - missions that always anger Beijing, Reuters reported.
China claims sovereignty over the island of Taiwan and says it has jurisdiction over the strait. Taiwan and the United States dispute that, claiming the strait is an international waterway.
The US Navy's 7th fleet said a P-8A Poseidon maritime patrol aircraft had flown through the strait "in international airspace", adding that the flight demonstrated the United States' commitment to a free and open Indo-Pacific.
"By operating within the Taiwan Strait in accordance with international law, the United States upholds the navigational rights and freedoms of all nations," it said in a statement.
China's military criticized the flight as "public hype", adding that it monitored the US aircraft throughout its transit and "effectively" responded to the situation.
"The relevant remarks by the US distort legal principles, confuse public opinion and mislead international perceptions," the military's Eastern Theatre Command said in a statement.
"We urge the US side to stop distorting and hyping up and jointly safeguard regional peace and stability."
Taiwan's defense ministry said the P-8A flew in a northerly direction through the strait and that the Taiwanese military monitored it, adding the "situation was as normal".
In April, China's military said it sent fighter jets to monitor and warn a US Navy Poseidon in the Taiwan Strait, a mission that took place just hours after a call between the Chinese and US defense chiefs.
