Metro Manila (CNN Philippines) — With China saying it won't honor the United Nation's (U.N.) arbitral decision, Sen. Ping Lacson suggested there should be U.N. peacekeepers stationed in the West Philippine Sea to protect Filipino fishermen.

Lacson on Wednesday said a U.N. contingent deployed in the Philippines' 200-nautical mile exclusive economic zone (EEZ) would make China think twice about violating the arbitration ruling.

"With all its military might, I don't think gegerahin [ng China] yung United Nations. Makakalaban nila dun community of nations na," he said.

[Translation: With all its military might, I don't think China will declare war against the United Nations. Otherwise, they will face a community of nations.]

Peacekeepers, composed of military observers, police personnel, civilians, and volunteers from U.N. member-states, help maintain peace in areas of conflict.

There are currently 16 peacekeeping operations led by the U.N., most of them located in Africa.

A new peacekeeping operation requires a number of consultations among stakeholders, as well as a technical field assessment in the conflict area.

The U.N., however, says "success is never guaranteed" with peacekeeping.

But Lacson also reminded the government that before making any further moves to implement the tribunal decision, it would be important for the Philippines to hold bilateral talks first with China.

Foreign Affairs Secretary Perfecto Yasay previously said the Philippines might agree to China's request for bilateral negotiations after the arbitral award had been issued.

Lacson also lauded the Aquino administration for raising the dispute at an international court, instead of directly discussing it with China.
