Beijing has accused the US of violating Chinese borders
Wu Qian noted that a group of US Navy ships as part of the USS Antietam missile cruiser and the destroyer USS Higgins flew approximately nautical miles (about 12 km) from the islands, conducting maneuvers in the South China Sea.

Wu Qian:
Beijing’s claims were responded to by the United States, saying that “warships acted in full compliance with international standards and did not violate China’s sovereignty.” The US Marine Corps added that they would carry out "previously planned operations in the future."
For reference: The Paracel Islands (Xisha) are located approximately 200 km east of the Vietnamese coast and 230 km south of the Chinese island of Hainan. Consist, in fact, of two archipelagoes: Yongle and Xuande. The largest island is Dong Dao (Lincoln Island) with an area of only 1,6 square. km The remaining islands, respectively, are even more tiny. However, China is not so much interested in these "fragments" of land, as in the wealth of the sea in the area of this archipelago.
