China and the Philippines have had repeated confrontations in the waters over the past year, including around a warship, grounded in 1999 by Manila on the contested Second Thomas Shoal, which hosts a garrison.
Both countries said on Monday that their coast guard ships had collided near the disputed Sabina Shoal, located 140 kilometers west of the Philippine island of Palawan and about 1,200 kilometers from Hainan island, the closest Chinese landmass.
China claims almost the entire South China Sea.
The United States condemned the “dangerous actions” against “lawful Philippine maritime operations” on Monday after the latest clash.
“These actions are the latest examples of (China) using dangerous and escalatory measures to enforce its expansive and unlawful South China Sea maritime claims,” State Department spokesman Vedant Patel said, AFP reported.
Asked about Patel’s remarks on Tuesday, his Chinese counterpart Mao Ning defended Beijing’s “legal measures to safeguard its territorial sovereignty and maritime rights and interests.”
“The US is not a party in the South China Sea and has no right to intervene in maritime disputes between China and the Philippines,” Mao told a regular briefing.
“The US should stop provoking confrontation in the South China Sea, not disrupt regional stability and not escalate tensions,” Mao said.
