The Philippines and China are locked in an impasse at a lagoon in the South China Sea

Both countries claim the area is "an integral part" of their territory

Manila has sent a coast guard boat and pulled back a naval vessel from the scene

A third official Chinese ship has reportedly arrived at the lagoon

(CNN) —  

The Philippines said Wednesday that its largest naval vessel is engaged in a standoff with two Chinese maritime surveillance ships in a remote lagoon in the South China Sea.

But the tense situation is not yet resolved, as a Philippine coast guard boat remains at the scene, and a third Chinese ship has arrived, said Raul Hernandez, a spokesman for the Philippine Department of Foreign Affairs.

The Philippine Department of Foreign Affairs said the country’s navy had sent the BRP Gregorio del Pilar, a 378-foot cutter, to the area of Scarborough Shoal on Sunday after surveillance aircraft spotted eight Chinese fishing boats anchored inside the lagoon.

He said negotiations were continuing with the Chinese in the hope of finding a “diplomatic solution” to the impasse at Scarborough Shoal, which both countries claim is “an integral part” of their territory. Scarborough Shoal is about 200 kilometers west of the Philippine mainland.

“For now, the ball is on the side of the Chinese,” Hernandez said.

The Philippines sent the Gregorio del Pilar to the area of Scarborough Shoal on Sunday after surveillance aircraft spotted eight Chinese fishing boats anchored inside the lagoon.

A boarding team from the Gregorio del Pilar went to inspect the Chinese fishing boats Tuesday morning and found “large amounts of illegally collected corals, giant clams and live sharks” inside one of the boats, the Department of Foreign Affairs said in a statement.

Later Tuesday, the Gregorio del Pilar reported that the two Chinese surveillance ships had arrived and taken up a position at the mouth of the lagoon, blocking the way to the fishing boats and “preventing the arrest” of the fishermen. The situation remained the same Wednesday morning, the Philippine statement said.

The Philippines said Thursday that it had sent the coast guard vessel to support the Gregorio del Pilar. It also reported the arrival of the third Chinese vessel, which it said was from China’s Bureau of Fisheries.

The Chinese Embassy in Manila has complained to the Philippine authorities about “the harassment of Chinese fishermen,” China’s official news agency reported Wednesday.

China has “urged the Philippine side to stop immediately their illegal activities and leave the area,” Xinhua reported, saying that the fishermen were taking shelter in the lagoon “due to harsh weather conditions.”

The embassy is “still engaged in discussions with the Philippine Department of Foreign Affairs to seek a solution” and maintain peace and stability in the South China Sea, Xinhua said.

The South China Sea – a 1.3 million square mile patch of the Pacific Ocean bracketed by China and several Southeast Asian nations – is dotted with hundreds of largely uninhabited islands and coral atolls that are home to some of the world’s most diverse marine life. Also under its waves lie potentially huge reserves of natural gas and oil.

That prospect has peppered the sea with competing claims from China, Vietnam, the Philippines, Malaysia, Brunei and Taiwan. It has also resulted in frequent small-scale clashes. Last year, a spate of incidents took place between Chinese and Vietnamese vessels.
