Malacañang on Saturday slammed Vice President Leni Robredo for criticizing President Rodrigo Duterte’s openness to ignore the Philippines’ legal victory in the South China Sea and seal an energy deal with Beijing, saying she needs new advisers who can comprehend the maritime row.

The US Navy said that one of its destroyers had sailed close to the Chinese-controlled Paracel Islands in the South China Sea on Friday, asserting international freedom of navigation rights in the contested waters.

“Setting aside” the 2016 arbitral court ruling on the South China Sea is as good as abandoning it, Supreme Court (SC) Senior Associate Justice Antonio Carpio said yesterday.

Under Philippine law, President Rodrigo Duterte does not have the authority to "set aside" the July 2016 ruling issued by the Permanent Court of Arbitration, Supreme Court Senior Associate Antonio Carpio said.

Following President Rodrigo Duterte's declaration of setting aside the Philippines' victory in the South China Sea arbitration, Malacañang said that the proposed joint oil and gas exploration with China is not yet final.
