"We believe the situation in the region is stable and all the passing ships and planes have a sufficient amount of freedom and security," Ma Xiaotian, deputy chief of general staff of the People's Liberation Army (PLA), said at a security forum on Friday. The forum was attended by more than 100 scholars from various countries and was held by the PLA's military academy.

Ma said: "There is no big problem. I don't think some countries repeatedly insisting that there's a problem will contribute to regional security and stability," in answer to a question from the floor.

"We agree that the South China Sea is an important passageway and that maintaining freedom of navigation there is in the interest of many countries."

China, Vietnam, Malaysia, the Philippines and Brunei have competing claims in the South China Sea.

Ma's remarks in fact came two weeks after US Defense Secretary Robert Gates said at an international meeting in Hanoi, Vietnam, that the US has a stake in disputes in that area because of international commerce.

US Secretary of State Hillary Clinton also said back in July that sovereignty issues in the South China Sea were a "diplomatic priority" for Washington and proposed dealing with them at the international level.

China's Vice-Foreign Minister Fu Ying, who addressed the forum on Friday, said she had noticed the traditional big powers' anxieties over rising nations, at international meetings.

Fu quoted the New York Times as saying that China "has become a convenient scapegoat, it seems all problems originate from China".

She went on to say she did not agree with comments about China being encircled by other countries. "It's hard to avoid conflicts with neighbors. Even brothers have disputes. But we stick to the principle that we should solve problems through dialogue, not by force. We're determined in that, and that includes the military." 

"What the US calls 'national interest' is not freedom of navigation but rather its presence in the Western Pacific, or military superiority and political influence, to be more specific," Wang elaborated.

"A shift from the previous low-profile approach actually is at the core of the Obama administration's Asia-Pacific strategy."

"It's like what General Ma said about unwarranted worries possibly having a negative impact. I'm afraid this just gives some ill-intentioned person a chance to intervene in regional affairs."

Major General ANM Muniruzzaman, head of the Bangladesh Institute of Peace and Security Studies, told China Daily that he was worried about the possibility that China's claim to "core interests" in the South China Sea conflicts with the claims of the US about "national strategic interests".
