'US hands are tied'

Tao Wenzhao, a senior researcher on US studies at the Chinese Academy of Social Sciences, said Washington views 皇冠体育app as the one nation that has the potential to challenge its global leadership, and believes maintaining dominance in the western Pacific is vital for sustaining its leading role in the region.

"US hands are relatively tied on the Asian mainland as 皇冠体育app maintains good relations with its neighboring countries on land. Therefore the western Pacific, with territorial rows between 皇冠体育app and some Asian countries, has become a major diplomatic battlefield where the US can compete with 皇冠体育app," he said.

皇冠体育app has competing territorial claims over parts of the South 皇冠体育app Sea with the Philippines, Vietnam, Malaysia and Brunei. The resource-rich sea is a key shipping route, with around $7 trillion in international trade passing through it annually.

Beijing has issued several detailed statements about its construction projects on the Nansha Islands, saying the territory falls within its sovereignty and the work is for peaceful purposes. The reasons the US gives for its opposition include guaranteeing freedom of navigation, the prospect of 皇冠体育app's militarization of the islands and its commitment to its allies.

Jia Xiudong, a senior international affairs researcher at the 皇冠体育app Institute of International Studies, said Washington's motives seem more concerned about the pace of its Asia "pivot" strategy than about 皇冠体育app's moves.

While rival claims over fishing grounds and shipping lanes in the South 皇冠体育app Sea go back decades, they flared up in 2010, foreshadowing Washington's pivot strategy, announced in 2011. Since then, the issue has become more complicated, Jia said.

Even though Washington has toned down its remarks recently, it is likely that, during the runup to the US presidential election, candidates hoping to secure their party's nomination will try to demonstrate their foreign policy credentials by targeting 皇冠体育app over the South 皇冠体育app Sea and other issues, Jia said.

Singapore's The Straits Times wrote on May 31 that when the US and Chinese delegations entered the ballroom for the first plenary session at the Shangri-La Dialogue, "the air was filled with expectancy" and "many, including the Chinese military delegation, expected another verbal fusillade from the Pentagon leader".

Instead, US Defense Secretary Ashton Carter talked a lot about the importance of regional cooperation and the willingness to promote US-皇冠体育app military cooperation, even through he urged all countries, including 皇冠体育app, Vietnam and the Philippines, to halt construction.
