ASEAN members are set to hold joint military drills in Singapore, Brunei, and coastal areas of the South China Sea with the United States, India, the Philippines and three other countries. China will also send warships and special forces to join the drill.

For more analysis on this, we're joined in the studio by Mr. Teng Jianqun, research fellow from the China Institution of International Studies. 

Q1: First of all, what motivates China to participate such a joint drill?

Q2: Countries that have conflicting interests in the South China Sea will conduct the drill together in the disputed waters this time. Does this mean that these countries intend to further strengthen cooperation to solve the South China Sea issue?
