Obama looks to salvage Asia 'pivot' as allies fret about China

During Obama's four-nation tour of Asia that begins on April 23, his toughest challenge will be to reassure skeptical leaders that the United States intends to be more than just a casual observer and instead is genuinely committed to countering an increasingly assertive China in the region.

For Obama, the tricky part of the trip, which will include stops in Japan, South Korea, Malaysiaand the Philippines, will be deciding how to set limits on Chinain a way that soothes USallies in Asia but avoids stoking tensions with Beijing.

USofficials say the Obama administration's long-promised "rebalancing" of America's economic, diplomatic and security policy toward Asia is on track, largely unaffected by the attention demanded by the crisis in Ukraineor persistent troubles in the Middle East.

The Asia "pivot" - as the White House initially dubbed it - represented a strategy to refocus on the region's dynamic economies as the United Statesdisentangled itself from costly wars in Iraqand Afghanistan.

When Obama announced the eastward shift, the most dramatic symbol of the new policy was the planned deployment of 2,500 US Marines in northern Australia, where they would be primed to respond to regional conflicts. It took until this month to build up forces to 1,150 Marines based in Darwin, and the full contingent is not due to be in place until 2017.

Obama will try to put those concerns to rest while in Manila, where Philippine officials say he is expected to sign a security pact that will allow for increased use of Philippine bases by US ships, aircraft and troops.

Manila's acceptance of a beefed-up US military presence, a politically sensitive issue in the independent-minded archipelago nation, would reveal the scale of Philippine anxiety over China.

The Philippine Senate voted to evict the US military from their bases in 1991, ending 94 years of American military presence in the Philippines, and has only gradually allowed the return of US forces for limited operations during the past decade.

The Philippine government is struggling to keep control of Second Thomas (local name: Ayungin) Shoal, where it has a military outpost on a reef surrounded by Chinese coastguard ships. The outpost itself is a huge, rusting World War Two transport vessel that the Philippine navy intentionally ran aground in 1999 to mark its claim.

Eight or so Filipino soldiers live there for three months at a time in harsh conditions on a reef that Manila says is within its 200-nautical mile exclusive economic zone. China, which claims 90 percent of the South China Sea, says the shoal is part of its territory.

Last month, a US surveillance plane was spotted overhead as a Philippine vessel dodged Chinese coastguard vessels to deliver supplies and fresh troops to the outpost.

Such US aircraft normally conduct their missions at higher altitudes, so the fact that its flyover was in full view of journalists monitoring the incident on the surface below suggested that the United States wanted to make its presence known. A Chinese plane and a Philippine military aircraft also flew above the area at different intervals.

The Obama administration has promised that the United States will reposition naval forces so that 60 percent of its warships are based in Asia-Pacific by the end of the decade, up from about 50 percent now. But as the US military budget contracts, that likely would represent part of a shrinking US defense pie.

Obama's aides brush aside complaints about the US follow-through on the pivot strategy, saying that no matter how much attention Washington devotes to friends and partners in the region, the allies will always want more from their superpower friend.

"Questions by Asia-Pacific allies about the degree of American commitment has been a constant component of our relationship for 60-plus years. It's not new," said a senior US official, who asked not to be identified because he was not authorized to comment publicly. "It doesn't mean the US won't do more to work with them."

Since then, negotiations have dragged on over a proposed US-led trans-Pacific trade pact that is widely seen as the economic centerpiece of Obama's pivot strategy.

In this tense regional climate, Obama can be expected to appeal directly to Asian leaders to have faith in America's resolve to keep China in check and discourage any notion that Beijing could emulate Russia's takeover of Crimea by seizing contested islands and shoals from its neighbors.

"Among countries in Asia, there has been an increase in the level of anxiety about what lessons China may be drawing from Russia and Ukraine," the senior US official said.

While sticking to a US refusal to take sides in the maritime disputes, Obama will seek to reassure South Korea, Japan and the Philippines that Washington is "fully committed to our defense treaties" with them, the official said.

Tokyo and Beijing are locked in a bitter row in the East China Sea over tiny, uninhabited isles administered by Japan, especially since China announced the creation of a controversial new air defense zone covering the area, which the Japanese call Senkaku and the Chinese call Diaoyu.

Relations between Japan and China have been further poisoned by Japanese Prime Minister Shinzo Abe's visit to a controversial shrine for war dead seen as a symbol of Japan's past militarism - a move that drew US criticism as well.
