The Philippines’ presidential palace has opted to say little for now about China’s recent activities in the South China Sea, including its erection of a monument on Kagitingan Reef and landing military planes on another reef within the Philippines’ territory in the strategic waterway. Presidential spokesman Harry Roque said in a television interview on Wednesday that the Department of Foreign Affairs was studying diplomatic actions it could take regarding China’s construction of the monument and its landing of military transport planes on Panganiban Reef. Lawmakers and legal experts have been calling on the Duterte administration to protest China’s landing of military transport planes on Panganiban Reef in January.
