Chinese coastguards have blocked and used water cannon on two Philippine supply boats heading to a disputed atoll occupied by Filipino marines in the South China Sea, Manila’s top diplomat says.
The move provoked a warning from the Philippine government that its vessels are covered under a mutual defence treaty with the United States.
Philippine Foreign Secretary Teodoro Locsin said no one was hurt in the incident on Tuesday, but the two supply ships had to abort their mission to provide food supplies to Filipino forces occupying the Second Thomas Shoal, which lies off western Palawan province in the Philippines’ internationally recognised exclusive economic zone.
Mr Locsin said in a tweet the three Chinese coastguard ships’ actions were illegal and he urged them “to take heed and back off”.

His government has conveyed to China “our outrage, condemnation and protest of the incident”, Mr Locsin said, adding “this failure to exercise self-restraint threatens the special relationship between the Philippines and China” that President Rodrigo Duterte and his Chinese counterpart Xi Jinping have worked hard to nurture.
In Beijing, Chinese Foreign Ministry spokesman Zhao Lijian said China’s coastguard had upheld the country’s sovereignty after the Philippine ships entered Chinese waters at night without permission.
The incident is the latest flare-up in the long-simmering territorial disputes in the strategic waterway, where China, the Philippines, Vietnam, Malaysia, Brunei and Taiwan have overlapping claims.
China claims virtually the entire waterway and has transformed seven disputed shoals into missile-protected island bases, ratcheting up tensions.
Philippine national security adviser Hermogenes Esperon told reporters in Manila two Chinese coastguard ships blocked the two wooden-hulled supply vessels.
A third coastguard ship “water cannoned the two for one hour”, he said.
The Philippines plans to deploy coastguard and Bureau of Fisheries vessels instead of navy ships to back up its forces and enforce its fishing laws at Second Thomas Shoal, which Filipinos call Ayungin and China refers to as the Ren’ai reef, Esperon said.
The number of Chinese surveillance ships has increased in recent weeks in the far-flung atoll and also around Thitu, a larger Philippine-occupied island in the Spratly archipelago in the South China Sea’s most hotly contested area, he said.
“We will continue the resupply and we do not have to ask the permission of anybody because that is within our territory,” Esperon said.
The Philippine military deliberately ran aground a World War II-era warship, the BRP Sierra Madre, at the submerged atoll in 1999 to fortify its claim and provide a shelter to a small contingent of Filipino marines.
The Sierra Madre is now effectively a rusty shipwreck but the Philippine military has not decommissioned it. That makes the ship an extension of the government and means any attack on the ship is tantamount to an assault against the Philippines.
Washington has no claims in the busy waterway but has patrolled the region with its navy ships and aircraft to assure its allies, including the Philippines, and ensure freedom of navigation and overflight.
China has repeatedly warned the US to stay away from the disputed waters and not meddle in what it says is a regional issue.
