It was the third "freedom of navigation operation" during Trump's presidency.
A U.S. warship sailed close to a Chinese man-made island in the disputed South China Sea in an operation that challenged China's vast territorial claims in busy worldwide waters, a U.S. Navy official said Thursday.

The South China Morning Post ran an editorial in late July denouncing USA freedom of navigation patrols as "ineffective" because they don't seem to have influenced Beijing's behavior at all, and yet also "risky" because they might push Beijing too far.
The U.S.is reportedly concerned that China's construction of artificial islands and build-up of military facilities in the South China Sea are meant to restrict nautical movement in the area.
Under worldwide law, countries can claim territorial sea up to 12 nautical miles from islands under their sovereignty.
The US does not recognise China's claims to the area.
"We are continuing regular FONOPs, as we have routinely done in the past and will continue to do in the future", he added.
The US official said the interactions were all "safe and professional", with the operation of the USS McCain lasting about six hours from start to finish.
A spokesman for the Chinese Foreign Ministry, Geng Shuang, said in a statement on its website late Thursday that the passage by the John S. McCain violated Chinese and worldwide law and "did serious harm to Chinese sovereignty and security".
"However, some parties from outside continue to meddle in the region under the guise of free navigation", Geng said. "All operations are conducted in accordance with global law and demonstrate that the United States will fly, sail, and operate wherever worldwide law allows".
Geng said China "has indisputable sovereignty over the Nansha Islands (Spratly) and their adjacent waters", and called for a dialogue between Beijing and the governments of the Association of Southeast Asian Nations member countries to solve the maritime dispute.
"It is clear who is not willing to see stability in the South China Sea and who is the major factor pushing for militarization in the South China Sea".
"The US military's provocative actions will only encourage the Chinese military to further strengthen the defense capacity building and firmly defend national sovereignty and security", Qian said.
