MANILA, Philippines — The government should review its policy of "appeasement and accommodation" toward China, according to Senate Minority Leader Franklin Drilon, saying that such a stance did not necessarily translate into economic benefits for the country.

Drilon issued the statement amid reports of increasing China's militarization of the South China Sea conflict and of its coast guard's taking of Filipino fishermen's catch on Scarborough Shoal.

According to Drilon, President Rodrigo Duterte should reevaluate his policy of appeasement toward China as records showed that it was not resulting in increase in trade and investments and in tourist arrivals in the country.

"I think the government should review the policy of appeasement and accommodation on China," Drilon said during the Kapihan sa Senado forum.

Drilon cited the case of Vietnam which had been vocal in asserting its rights and condemning China for its aggressiveness in staking its claim to the disputed waters, a region believed to be holding vast reserves of natural resources.

Drilon said that foreign direct investments from China for the year 2017 stood at $31 million, "very minimal" compared to the $600 million from Japan and $160 from the United States.

"Vietnam, in 2017, got from Chinese direct investment was US$2.170 billion contrasted to our US$31 million. That indicates the non-connection between the policy of appeasement as contrasted to Vietnam’s policy of confrontation," he said.

Bilateral trade between the Philippines and China stood at $21.94 billion in 2016 while that between Vietnam and China was at $71.85 billion, he said.

Tourist arrivals in Vietnam from China reached four million in 2017 while in the Philippines it was only 968,447.

Duterte has been trying to forge closer ties to China in an effort to court Chinese money and investments in the country.

He has also chosen to take a non-confrontational approach to China's increasing militarization of the South China Sea dispute and to back-burn a 2016 United Nations-backed tribunal ruling invalidating much of Beijing's expansive claims to the disputed seas.

Drilon also urged the Senate to conduct an audit of the country's foreign policy, saying that the chamber is the partner of the executive department in conducting the country's foreign relations.

"It is only correct that the Senate be informed of how foreign relations are being conducted; otherwise we will be in the dark, and therefore, I support that proposed review of our relationship with China," Drilon, a former justice secretary and Senate president, said.

"We are making the call addressed to the chair of the committee to assert the Senate’s role as a partner in the conduct of foreign affairs. The Senate lead should take a serious look at this and assert the role of the Senate in this area."

Drilon said that the Philippines should be more assertive of its rights in the South China Sea and of the 2016 ruling.

Aside from China and the Philippines, a host of regional countries also have competing claims to the seas, through which $3 trillion worth of trade annually passes.
