The military chiefs of the Shanghai Cooperation Organization's (SCO) member states are meeting in Beijing on August 28.
The chiefs of general staffs of China, Russia, Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan are expected to discuss, among other things, regional security after most foreign troops leave Afghanistan at the end of 2014.
The SCO is a security alliance dominated by Russia and China and seen as a counterweight to NATO.
On August 29, its six army chiefs will monitor the final stage of ongoing anti-terrorist drills in China.
Around 7,000 servicemen from China, Russia, Kazakhstan, Kyrgyzstan, and Tajikistan are participating in the six-day exercises.
The drills, dubbed Peace Mission 2014, involve ground troops, aviation, air defense systems, and radio-electronic warfare.
