A LEADING Chinese military strategist called planned United States troop exercises near its borders a provocation and accused the Obama administration of seeking to encircle China and of a "chaotic" policy toward the country.

"On the one hand, it wants China to play a role in regional security issues. On the other, it is engaging in an increasingly tight encirclement of China and constantly challenging China's core interests," Rear Admiral Yang Yi wrote in the Liberation Army Daily.

The Pentagon is planning new joint naval exercises with South Korea that will send a US aircraft carrier into the Yellow Sea between China and the Korean Peninsula.

Yang, who works at China's National Defence University, warned that friction over the exercise reflected broader instability in relations with China. "Rarely has there been such wavering and chaos in US policy toward China," he wrote.

Last month, the US and South Korea held a joint naval drill in the Sea of Japan off the Korean Peninsula, which was condemned by China.

The US and South Korea have said their exercises are a warning for North Korea, which they blame for sinking a South Korean ship in March.

"As well as expressing its dissatisfaction to North Korea, the United States even more wants to send a signal to other countries in the northeast Asia region -- that the United States remains the world's top military power," wrote Yang.

"Anyone clear-sighted can see that this carries something of a warning to China."
