Beijing claims USS Milius “illegally entered" its "territorial waters without approval" but the US said it was conducting routine operations in international waters off the disputed Paracel Islands.
The United States has denied Chinese claims that its military had driven away an American guided-missile destroyer from operating around disputed islands in the South China Sea as tensions rise in the region between the two powers.
The US Navy's 7th Fleet said that a statement from China's Southern Theatre Command that it had forced the USS Milius away from waters around the Paracel Islands — called Xisha by China — was “false.”
“USS Milius is conducting routine operations in the South China Sea and was not expelled,” said Navy spokesman Luka, in response to a query from The Associated Press news agency.
"The United States will continue to fly, sail and operate wherever international law allows,” Bakic added.
Bakic would not comment on whether the ship had been operating in immediate proximity of the Paracel Islands, which are in the South China Sea a few hundred kilometers (miles) off the coast of Vietnam and the Chinese province of Hainan, or whether there had been any sort of a confrontation.
China occupies the Paracel Islands, but they are also claimed by Taiwan and Vietnam.
Col. Tian Junli, a spokesperson for China’s Southern Theatre Command, said earlier that the Chinese navy had followed and monitored the USS Milius after it “illegally entered China's Xisha territorial waters without approval from the Chinese government, undermining peace and stability in the South China Sea.”
He said that the Chinese navy and air force then forced away "the US warship in accordance with the law.”

"The theatre troops will maintain a state of high alert at all times and take all necessary measures to resolutely safeguard national sovereignty, security as well as peace and stability in the South China Sea,” he said.
The incident comes amid growing tensions between China and the United States in the region, as Washington pushes back at Beijing's growingly assertive posture in the South China Sea and elsewhere.
China claims ownership over virtually the entire strategic waterway, through which around $5 trillion in global trade transits each year and which holds highly valuable fish stocks and undersea mineral resources.
The Philippines, Brunei, Malaysia, Vietnam and Taiwan also have competing claims.
Chinese ships have also been accused by neighbouring countries like Vietnam and the Philippines of repeatedly violating its exclusive economic zones.
The US itself has no claims to the waters, but has deployed Navy and Air Force assets to patrol the waterway for decades and says freedom of navigation and overflight is in the American national interest.
China has frequently accused the US of meddling in Asian affairs and demanding it leave the region where it has had a naval presence for more than a century.
Following the incident with the USS Milius, Chinese Foreign Ministry spokesperson Wang Wenbin told reporters in Beijing that “the US should immediately stop such violations and provocations.”
“China will continue to take all necessary measures to firmly safeguard national sovereignty and security and maintain peace and stability in the South China Sea,” he said.
