On May 6, 2011, in Kashi, Xinjiang Province, China, the Shanghai Cooperation Organization (SCO) launched a joint anti-terrorist exercise, “Tian Shan No. 2,” with the participation of China, Kyrgyzstan, and Tajikistan. This is the second of its kind following “Tian Shan No.1” back in 2006, in which China and Kazakhstan participated. The exercise included the following three areas: decision making, a hostage rescue force, and a fixed-point raid action. Law enforce officials from SCO member states observed the exercise, along with states with observer status.
