'Aggressive' Chinese warship forces US destroyer off course in South China Sea confrontation

A Chinese warship sailed within yards of an American destroyer - forcing it to change course - in an "unsafe and unprofessional" encounter as the US vessel was in contested waters in the South China Sea, an official said on Monday. The USS Decatur guided-missile destroyer was conducting what the US Navy calls a "freedom of navigation operation" on Sunday, when it passed within 12 nautical miles of Gaven and Johnson reefs in the remote Spratly Islands. The 12-mile distance is commonly accepted as constituting the territorial waters of a landmass. China claims nearly all of the South China Sea, though Taiwan, the Philippines, Brunei, Malaysia and Vietnam all claim parts of it. Beijing claims all of the Spratlys and has built a number of military installations on the islands. During the operation, a Chinese Luyang destroyer approached the USS Decatur in "an unsafe and unprofessional manoeuvre in the vicinity of Gaven Reef in the South China Sea," said Commander Nate Christensen, US Pacific Fleet spokesman.

The Chinese "destroyer approached within 45 yards of Decatur's bow, after which Decatur manoeuvred to prevent a collision." In a statement, the Chinese Ministry of Defence said that its ship had "given a warning to leave" to the vessel after she entered the area "without permission." "The US has repeatedly sent warships into the territorial waters near Chinese reefs and islands in the South China Sea," it said. The behaviour "gravely threatens China's sovereignty and security, gravely damages relations between China and the US and their militaries, and gravely injures regional peace and stability." Q&A | South China Sea dispute US-Chinese relations have been strained on multiple levels since Donald Trump became president in 2017. A trade war launched by Mr Trump has infuriated Beijing, as did his authorisation of a $1.3 billion arms sale to Taiwan, which China considers a rebel province. Washington last week enacted new tariffs against China covering another $200 billion of its imports. China has taken a series of retaliatory measures, including scrapping a US warship's planned port visit to Hong Kong and cancelling a meeting between the head of the Chinese navy and his American counterpart. On Monday, a US defence official said that security talks due to take place later this month in Beijing between Defence Secretary Jim Mattis and his Chinese counterpart had been cancelled.
