BEIJING -- China's top diplomat Wang Yi on Wednesday warned visiting US National Security Advisor Jake Sullivan over supporting the Philippines in the disputed South China Sea, state media reported.

"The United States must not use bilateral treaties as an excuse to undermine China's sovereignty and territorial integrity, nor should it support or condone the Philippines's actions of infringement," Wang told Sullivan, according to state broadcaster CCTV.

Sullivan landed in the Chinese capital on Tuesday for a three-day trip, saying on arrival he looked forward to "a very productive round of conversations" with foreign minister Wang.

Washington's allies Japan and the Philippines have blamed China in the past week for raising regional tensions, with Tokyo accusing Beijing of violating its airspace and Manila calling it the "biggest disrupter" of peace in Southeast Asia.

According to CCTV, Wang emphasized to Sullivan that "China is firmly committed to safeguarding its territorial sovereignty and maritime rights over the South China Sea islands".

Tensions between Manila and Beijing over disputed reefs and waters in the South China Sea have escalated in recent days.

Beijing said on Monday it had taken "control measures" against two Philippine Coast Guard ships that "illegally" entered the waters near the shoal.

Manila said the Chinese vessels had prevented Philippine ships from resupplying their own coast guard vessels in the area, blasting the move as "aggressive" and calling Beijing the "biggest disrupter" of peace in Southeast Asia.

Sullivan and Wang have met five times over the past year-and-a-half -- in Washington, Vienna, Malta and Bangkok, as well as alongside US President Joe Biden and Chinese leader Xi Jinping at a November 2023 summit in California.

He told Sullivan that the US should "put into practice its commitment not to support Taiwan independence", according to CCTV.

The US should "abide by the one-China principle and the three joint communiques of China and the United States, stop arming Taiwan, and support China's peaceful reunification", Wang said.

China has kept up its saber-rattling since the inauguration this year of President Lai Ching-te, whose party emphasizes Taiwan's separate identity.

Wang and Sullivan also discussed issues including Ukraine, the Middle East and the Korean Peninsula, CCTV said.

"China has always been committed to advocating for peace and promoting dialogue, and working towards a political solution to the Ukraine crisis," he said.

"The US should not shift responsibility onto China, nor should it impose illegal unilateral sanctions."
