China expressed its "strong dissatisfaction" with Japan's 2011 defense white paper Wednesday, saying it contains irresponsible comments on China's national defense construction.

Ma Zhaoxu, Chinese Foreign Ministry spokesperson, said "the Japanese 2011 defense white paper made carping and irresponsible comments on China's national defense construction."

The China-related content in the white paper was published on August 2, Xinhua reported.

China's reinforcement of national defense and military modernization drive is not targeting any other country and entirely for safeguarding its national sovereignty, security and territorial integrity, Ma said.

He said China's development offers significant opportunities to all countries in the world including Japan. China has not and will never be a threat to any other country.

He said China hopes Japan can learn from the past, seriously reflect on its own defense policy and do more to deepen mutual trust with neighboring countries, maintain regional peace and stability, not the contrary.

He also reaffirmed China's adherence to the path of peaceful development and pursuit of defensive national defense policy, Xinhua reported.
