China's military said on Monday that a Philippine vessel "illegally entered" waters near Scarborough Shoal without authorisation and it urged the Philippines to immediately stop its provocations.
China and the Philippines have had several confrontations in disputed waters in the South China Sea, recently trading accusations about a collision between a Chinese coastguard vessel and a boat from the Philippines.
"We are urging the Philippine side to immediately stop its infringement and provocations, and earnestly avoid further escalation," said senior colonel Tian Junli, a spokesperson for the People's Liberation Army Southern Theater Command.
The Scarborough Shoal is claimed by China, the Philippines and Taiwan.

"The Philippine side's actions have seriously violated China's sovereignty and international law and basic norms governing international relations, and are prone to misunderstanding and miscalculation," Tian said.
He said China followed, monitored, warned and blocked the ship in accordance with the law.
