The Philippine navy transported food and other supplies to a territorial ship outpost in a shoal in the South China Sea without any confrontation with Chinese forces guarding the disputed area, officials have said.

The Philippine delivery of supplies and military personnel on Thursday to the Second Thomas Shoal was the third such trip that did not lead to any confrontation since July, when both sides signed a rare deal to stop an alarming spike in violent confrontations.

“The Armed Forces of the Philippines continues to uphold its mandate of safeguarding Philippine sovereignty and ensuring the welfare of its stationed personnel in the West Philippine Sea,” military spokesperson Colonel Xerxes Trinidad said, using the Philippine name for the South China Sea.

“There were no untoward incidents during the mission,” Colonel Trinidad said.

The Philippines occupied the shoal by permanently beaching a navy ship in its shallows in 1999, prompting China, which also claims it, to surround the atoll with its coastguard and naval forces in what has been a continuing territorial stand-off.

Called Ayungin by the Philippines and Ren’ai Jiao by China, the shoal had been the most dangerous flashpoint in the South China Sea and became the scene of increasingly violent confrontations starting last year that alarmed other governments, led by the US.

The deal, which has not been made public, outlines a temporary arrangement that lets the Philippines transport supplies and fresh batches of Filipino forces to Manila’s ship outpost without clashing with China’s coast guard, navy and suspected militia ships guarding the shoal.

Neither side conceded its territorial claims under the deal, which only applies to the Second Thomas Shoal, according to Philippine officials.

The agreement was reached after China agreed to drop a demand for the Philippines to notify China in advance of any trip to the shoal and for Chinese forces to board Philippine supply vessels for inspection, two Philippine officials told The Associated Press in July.

They spoke on condition of anonymity for lack of authority to discuss the negotiations publicly.

It is the first known agreement by China with any one rival claimant country over a specific shoal in the South China Sea, which Beijing claims almost in its entirety.

Before the deal was reached, Chinese coastguard and navy forces had used powerful water cannons and dangerous blocking maneouvers to prevent Philippine supply vessels from reaching Manila’s fragile outpost at the shoal — the long-grounded and rusting warship, the BRP Sierra Madre.

In the worst confrontation, Chinese forces on speedboats repeatedly rammed and then boarded two Philippine navy boats on June 17 to prevent Filipino personnel from transferring food and other supplies including firearms to the BRP Sierra Madre, the Philippine military said.

The Chinese forces seized the Philippine navy boats and damaged them with machetes and improvised spears.

They also seized seven M4 rifles, which were packed in cases, and other supplies in a chaotic face-off that wounded several Filipino navy personnel.

The assault was captured in video and photos that were later made public by Philippine officials.

China and the Philippines blamed each other for the confrontation. The US, Japan and Australia were among those who condemned the Chinese actions at the shoal.

While clashes have stopped at the Second Thomas Shoal, sporadic confrontations have continued elsewhere in the South China Sea.

Vietnam, Malaysia, Brunei, Taiwan and, at times, Indonesia, have also been involved in the long-seething territorial disputes in the busy waterway.
