MANILA—The Philippines’ defence minister on Tuesday ordered the military to investigate a report by a U.S.-based tech firm that hundreds of Chinese vessels were dumping sewage into contested areas of the South China Sea.
China maintains a constant presence of coastguard and fishing boats in the South China Sea to assert its claim of sovereignty, including hundreds in the Spratly islands, where the Philippines, Brunei, Taiwan, Vietnam, and Malaysia also have claims.
