Ministry rejects Manila's claims on Ren'ai Reef, calls its actions dangerousChina "will not turn a blind eye" to the Philippines' repeated provocations and harassment in the South China Sea, although the nation is always committed to resolving differences through dialogue and consultation, a spokesman for the Ministry of National Defense said.
Wu Qian, the spokesman, made the remarks on Thursday at a news conference in Beijing, rejecting the groundless accusations made by the Philippines regarding China's Ren'ai Reef.
Several Philippine officials have recently claimed that China Coast Guard vessels used water cannons to attack Philippine ships near the reef and rammed at least one of them, triggering regional tensions.
Calling these allegations completely false, Wu said the Philippine side, in disregard of repeated warnings from the Chinese side, insisted on sending vessels to intrude into the adjacent waters of China's Ren'ai Reef and provocatively rammed a China Coast Guard vessel.
He said that although the Philippines claimed it was transporting humanitarian supplies to its grounded warship near the reef, those Philippine resupply vessels actually carried journalists, who propagated plenty of disinformation.
Wu said that China has indisputable sovereignty over the Nansha Islands, including Ren'ai Reef, and their adjacent waters.
