"We hope the United States will strictly honour its commitment of not taking positions or sides on territorial sovereignty issues," said Chinese Foreign Ministry spokesperson Hong Lei in response to the reported remarks by Robert Thomas, commander of the US Navy's Seventh Fleet.
In his comments, Thomas had also said his fleet would provide support in patrolling.
Hong said Thomas' remarks "will by no means help resolve the South China Sea disputes properly or contribute to peace and stability in the South China Sea (SCS)".
He said that it is China's long-standing commitment to resolve the disputes in the SCS through negotiations and consultations with the countries directly concerned.
According to Hong, China and the ASEAN have proposed a joint initiative in which they will safeguard peace and stability in the SCS independently of other nations.
He urged the US side not to make irresponsible remarks any longer and instead do more that is conducive to boosting mutual trust and regional peace and stability.
