Aerospace should be used for peaceful purposes only, and China is ready to take part in any international cooperation to ensure aerospace security, President Hu Jintao said on Friday.

Hu made the remarks while meeting 30 heads of foreign air force delegations in the Great Hall of the People in Beijing.

The delegations are in the capital to attend an international military forum on peace and development to mark the 60th founding anniversary of the People's Liberation Army Air Force (PLAAF), which was founded on Nov 11, 1949, just over a month after the People's Republic of China was established.
