MANILA » The United States will provide the Philippines’ security forces with $40 million in new assistance in part to help the country protect its territorial waters amid rising tensions with China over disputes in the South China Sea, U.S. Secretary of State John Kerry said Tuesday (Monday in Hawaii) while urging all the nations involved to "lower the intensity."

The money, from a U.S. program known as the Global Security Contingency Fund, will be spent over three years and will be split between improving the Philippines Coast Guard’s maritime security abilities and boosting counterterrorism capacity for the Philippines National Police in the nation’s restive southern islands, where Washington has also backed a decade-long campaign against al-Qaida-linked local militants.

The new aid is intended to complement a $32.5 million assistance package, which Kerry announced Monday in Vietnam, that will help southeast Asian nations protect their territorial waters. Up to $18 million of that money will go to provide the Vietnamese Coast Guard with five new fast patrol boats.

Both Vietnam and the Philippines have competing claims with China over territory in the South China Sea and are concerned with growing Chinese assertiveness after Beijing’s unilateral declaration of an East China Sea air defense zone. That zone has dramatically raised tension between China and Japan.

"The United States does not recognize that zone and does not accept it," Kerry said during a news conference Tuesday with Philippines Foreign Secretary Albert del Rosario. "The zone should not be implemented and China should refrain from taking similar unilateral actions elsewhere in the region, particularly over the South China Sea."

Chinese officials have suggested that a similar zone could be established over the South China Sea.

Del Rosario said: "China, in doing this, effectively is attempting to transform an air zone into its own domestic airspace, and we think that this could lead to compromising freedom of flight, in terms of civil aviation, and also compromise safety and security of affected nations."

If China establishes an air defense zone in the South China Sea, del Rosario said, "that for us will be a problem."

Kerry said the United States would stand with its friends in the Asia-Pacific.

"The United States strongly opposes the use of intimidation, coercion or aggression to advance territorial claims and I assured the foreign secretary that the United States remains firmly committed to the security of the Philippines and of the region," he said.

Kerry stressed the need for negotiated resolutions to the disputes. "The United States will stand with our friends in this region who are asserting their (claims) through that kind of legal, peaceful process," he said. "I hope that ultimately the leaders in China will see the wisdom of engaging."

The Philippines lost control of a disputed reef in the South China Sea last year after a standoff with China. The U.S. is also helping equip the Philippines with ships and radar, and is also in negotiations with Manila to increase the American military presence there. However, officials have stressed they have no plans to reopen former U.S. military bases in the Philippines.

Kerry maintained that his announcements in the Philippines and Vietnam were not directly aimed at China but rather a normal part of the Obama administration decision to refocus on Asia.

"We do not support unilateral actions that have the impact of being provocative and raising the temperature of potential conflict," Kerry said. "We are not approaching this with any particular view towards China except to say that when China makes a unilateral move we will state our position and make clear what we agree or disagree with."

However, the increased aid is almost certain to anger Beijing, which bristles at what it sees as U.S. interference in areas it views as China’s "core interest." Beijing looks dimly on Washington’s push to increase the U.S. military presence and strengthen its alliances in Asia as it ends a decade of war in Iraq and Afghanistan, calling it an attempt to contain China.

In a reminder of the high stakes in play, U.S. and Chinese naval vessels came close to colliding in the South China Sea on Dec. 5, the most serious incident between the two navies since 2009.

The U.S. Pacific Fleet said Saturday that the USS Cowpens was operating in international waters and had to maneuver to avoid hitting China’s lone aircraft carrier. The Liaoning, a symbol of China’s ambition to develop a navy that operates farther from its own shores, only entered service last year and was on its first sea trials in the South China Sea.

Beijing has not formally commented on the incident, but the state-run Global Times newspaper reported Monday that the U.S. ship had first harassed the Liaoning and its group of support ships, getting too close to a Chinese naval drill and entering within 30 miles of the Chinese fleet’s "inner defense layer."

As China expands its navy’s reach and starts to challenge decades of American military predominance in the region, it’s becoming more common for vessels of the two nations to operate in close proximity. The Obama administration has made it a priority to seek closer military cooperation with China to prevent misunderstandings that could spark a clash — part of a broader push to foster friendly ties between the established world power and the emerging one.

Kerry is in the Philippines on the last leg of a trip to the Middle East and Asia. Before heading for home Wednesday he will visit the Philippine city of Tacloban, which was hard hit by last month’s deadly Typhoon Haiyan. The U.S. was a major contributor of relief after the disaster and Kerry is expected to announce additional support during a brief inspection tour of the storm-ravaged area.
