On the contrary, Manila's recent decision to send a warship to the island and dispatch personnel for a forced inspection of Chinese fishing boats triggered the existing tension, said the Chinese spokesman.

"Manila's moves unavoidably gave rise to massive concerns over security in the related waters," Liu added.

Yang Baoyun, a professor of Southeast Asian studies at Peking University, said Manila's current remarks and stances "show few signs of sincerity" to resolve the dispute.

No country is allowed to misuse international laws to serve its interest, Yang said, adding that Manila did not lay territorial claim to the island until 1997.

Hernandez also said on Monday that Manila planned to exchange views with Washington on the island dispute during the upcoming "2+2" US-Filipino talks, scheduled to start on Monday.

"Generally, a country does not take sides on other countries' sovereignty disputes. And we have noticed that none of the other countries has taken sides on the issue," said Liu, the spokesman.

Manila's standoff against Beijing in the waters of Huangyan Island entered its fifteenth day on Tuesday.

On April 10, 12 Chinese fishing boats were harassed by a Philippine warship while taking refuge from harsh weather in a lagoon near the island. Two Chinese patrol ships in the area later came to the fishermen's rescue, and the warship left.

The Chinese fishermen returned home, but the standoff remains. There were still two Philippine vessels and one Chinese ship in the waters on Tuesday.

Xinhua News Agency on Monday reported that two Chinese vessels, a Fishery Administration ship and a Chinese Maritime Surveillance ship, left the area on Sunday.

"The withdrawal of the two ships proves once again that China is not escalating the situation as some people said, but de-escalating the situation," said Zhang Hua, spokesman for the Chinese Embassy in the Philippines.

China is ready to settle this incident through friendly diplomatic consultations, Zhang added.
