The Senate will investigate the reported deployment by China of missiles on three Philippine-claimed reefs in the Spratly archipelago, and press the Department of Foreign Affairs (DFA) to explain how it will respond to Beijing’s actions, Senate leaders said on Sunday. An opposition lawmaker also said on Sunday that he would file a resolution in the House of Representatives for an investigation of China’s “creeping invasion” of Philippine territory in the South China Sea. US news network CNBC, citing sources with direct knowledge of US intelligence reports, said last Wednesday that China had deployed antiship cruise missiles and surface-to-air missile systems on Kagitingan, Zamora and Panganiban reefs in the Spratly archipelago.
