BEIJING, Jan. 3 (Xinhua) -- A collection of China's nine white papers issued in 2011 has been published in both Chinese and English, according to a statement issued by the publisher on Tuesday.

The white papers are titled, "China's National Defense in 2010," "China's Foreign Aid," "Sixty Years Since the Peaceful Liberation of Tibet," "China's Peaceful Development," "The Socialist System of Laws with Chinese Characteristics," "New Progress in Development-oriented Poverty Reduction Program for Rural China," "China's Policies and Actions for Addressing Climate Change (2011)," "China's Foreign Trade" and "China's Space Activities in 2011."

The white papers were all published by the Information Office of the State Council on behalf of the Chinese government.

The latest one on space activities was issued last Thursday.
