A retired senior Chinese diplomat believes that China, the United States and Southeast Asian nations should peacefully settle disputes in the South China Sea.

Wang Yingfan, China's permanent representative to the United Nations from 2000 to 2003, said Americans should understand that China has never created any obstacles to freedom of navigation in the region.

The former vice-foreign minister said people who study international affairs understand why the US would send aircraft carriers and advanced aircraft to the sea.

"It's not because freedom of navigation is being affected," he said on Monday, without further elaboration.

Wang, who was heading a Foreign Ministry Policy Advisory Committee delegation in the US, made the comment in a talk on China's foreign policy and China-US relations at American University on Monday.

Many Chinese believe the US has been rallying its allies to gang up on China in pursuit of its pivot-to-Asia strategy and to keep its primacy in the region, where China's influence has grown significantly. China is the largest trading partner for most countries in that area.

Wang warned that the US should exercise restraint.

"If you do too much, China has to react," he said.

Wang believes that how much Chinese military hardware will be brought to the islands in the South China Sea depends to a large extent on what the US will do.

China has long complained about the frequent US military surveillance off the Chinese coasts, regarding it as a major obstacle to improving bilateral military-to-military relations.

Wang, also a former Chinese ambassador to the Philippines, recalled his first assignment in the Southeast Asia nation in mid-1970s that the Philippine map does not include some of the islands in disputes these days.

He regretted that the Philippines did not even accept China's goodwill and generosity for shelving disputes and seeking joint development.

Wang believes it's a bad idea for some Americans to suggest that the Chinese government clarify the Nine Dash Line in the South China Sea because it will trigger more disputes over sovereignty and further arouse the nationalistic sentiment in the countries involved, making it harder for the governments to reach a solution.
