MANILA: The Philippines is working hard to bring China back to the table for talks to resolve differences in the South China Sea, foreign affairs secretary Enrique Manalo said on Tuesday. The two countries held a working group meeting last week in preparation for a potential bilateral consultation mechanism meeting in July, Manalo told a senate inquiry on Tuesday. "Whatever confidence-building measures we achieve, they will be not at the expense of promotion of our sovereignty, sovereign rights, as well as our rights and jurisdiction on the West Philippine Sea," Manalo said. The Philippines uses the West Philippine Sea name for the portion of South China Sea that it claims.
