China's navy Commander Wu Shengli warned his U.S. counterpart there could be “seriously pressing situation between the frontline forces from both sides on the sea and in the air, or even accidental conflits" if the United States continues with its provocative acts in the South China Sea at a video teleconference on Thursday night.

The teleconference between the Chinese Admiral and U.S. navy’s Chief of Naval Operations Admiral John Richardson was called after the U.S. destroyer USS Lassen entered waters near Zhubi Reef, part of China's Nansha Islands, without the permission of the Chinese government on Tuesday.

“Such dangerous and provocative acts have threatened China's sovereignty and security and harmed regional peace and stability," Admiral Wu said.

He warned that China will "have to take all necessary measures to safeguard sovereignty and security" if the United States persists going its own way and ignoring China's concern.

"(I) hope the U.S. side cherishes the good situation between the Chinese and U.S. navies that has not come easily and avoids these kinds of incidents from happening again," Wu added at the teleconference.

The naval chiefs agreed to maintain dialogue and follow protocols to avoid clashes at the teleconference. The scheduled port visits by U.S. and Chinese ships and planned visits to China by senior U.S. navy officers will also remained on track, Reuters reported earlier today.

US no hope to win S.China Sea showdown

Calling the USS Lassen's intrusion a "regular occurrence," the US military put a gloss on its recent brazen provocation against China in the South China Sea, implying that more warships might be sent within the 12 nautical mile-limit around China-controlled islands. China will have to escalate its countermeasures if Washington does so, and the situation will worsen for the US.

Commentary: The U.S. should never play with fire in South China Sea

The U.S. move was long planned. U.S. media said in May that the U.S. navy wanted to “challenge” China’s construction projects in the South China Sea, and since September the U.S. navy has been laboring its views on South China Sea disputes and claiming to send a warship within 12 nautical miles of China's islands. The U.S. has long caused trouble in South China Sea disputes even though it is not one of the parties concerned to the South China Sea issue.
