ADDIS ABABA, March 14 (Xinhuanet) -- The African Union (AU) on Monday reiterated its One China policy and expressed support for China's anti-secession law to prevent Taiwan's secession from China.

"The anti-secession law adopted today by China's National People's Congress is of vital importance," said AU Commission Chairperson Alpha Oumar Konare when meeting with Chinese Ambassador to Ethiopia Lin Lin.

Konare said he would like to congratulate the Chinese government on the approval of the law.

"China's stance to oppose secession and achieve national reunification is very correct," he said, adding that the new law would play a very important part in China's sovereignty, territorial integrity, and even China's future development.

He said the AU adheres to its One China policy and regards Taiwan as part of China.

The adoption of anti-secession law "is not only a great successof China, but also a great success of Africa," he said.

The National People's Congress, China's legislature, on Monday passed the law which came into effect immediately after President Hu Jintao signed a presidential order to promulgate it later in day.
