Code-named "Tianshan-II (2011)," the drill featured how law enforcers and security personnel from the three countries have coordinated efforts to locate and crack down on "terrorists" in the border regions.

The anti-terror exercise consisted of three parts, namely decision-making and command, freeing abductees by force, and cleanup operation at designated venues.

The drill is the second such joint anti-terrorism exercise that China's law enforcement bodies have participated in within SCO framework.
