Military chiefs from the Shanghai Cooperation Organization (SCO) have agreed to improve joint antiterrorism operations.
The chiefs of general staffs of China, Russia, Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan met in Beijing on August 28.
Russian military chief Valery Gerasimov said terrorism, separatism, extremism, and drug trafficking pose a serious threat to joint security.
Chinese military chief Fang Fenghui said the situation around Afghanistan was becoming more complicated and "terrorists are rapidly infiltrating into Central Asia."
The SCO is a security alliance dominated by Russia and China and seen as a counterweight to NATO.
