The Philippines has protested against China’s ‘dangerous manoeuvres’ 20 times this year as tensions escalate over the disputed shoal.

The Philippines has summoned a Chinese diplomat, accusing Beijing of “harassment” and “dangerous manoeuvres” after its use of water cannon against two Philippine vessels during a patrol in the South China Sea.

The Ministry of Foreign Affairs called in China’s deputy chief of mission Zhou Zhiyong on Thursday, two days after the incident at a disputed shoal that left a Philippine coastguard vessel and another government boat damaged.

It was the 20th protest by the Philippines against the conduct of China’s coastguard and fishing vessels this year, the ministry said. It has made 153 complaints over the past two years.

“The Philippines protested the harassment, ramming, swarming, shadowing and blocking, dangerous manoeuvres, use of water cannons, and other aggressive actions of [the] China Coast Guard and Chinese maritime militia,” the ministry said in a statement.

China blockaded and seized the Scarborough Shoal from the Philippines in 2012.

The Philippines said the pressure in Tuesday’s water cannon incident was far more powerful than anything previously used, and that it tore or bent metal sections and equipment on the Philippine vessels.

Tensions have escalated over the Scarborough Shoal recently as the Philippines takes a more assertive approach in disputed areas while strengthening alliances with the United States and Japan.

A prime fishing patch used by several countries and close to major shipping lanes, the shoal falls inside the Philippine exclusive economic zone and is claimed by China, though no country has sovereignty over it.

China’s embassy in Manila said on Wednesday the atoll had always been China’s territory and urged the Philippines to cease infringements and provocations and not “challenge China’s resolve to defend our sovereignty”.

China claims almost the entire South China Sea, brushing off rival claims from other countries, including the Philippines, and an international ruling that its assertions have no legal basis.

Brunei, Malaysia and Vietnam also claim the parts of the sea around their coasts.
