He was president of COSPAR when the 36th COSPAR Scientific Assembly and Associated Events were held in Beijing in 2006. The joint COSPAR/CAS Jeoujang JAW Award was also established during Professor Bonnet’s presidency. The Award recognizes scientists who have made distinguished pioneering contributions to promoting space research, establishing new space science research branches and founding new exploration programs. This honor was the first international scientific award co-founded by CAS and an international organization. During the past five years, two COSPAR Capacity Building Workshops were held in China, providing many young Chinese researchers with the opportunity to enhance their research capabilities with concomitant impacts on the development of space science in China.
