Mid-ranking military officers and attachés from Afghanistan, Pakistan and Tajikistan, attended a symposium on counter terrorism at the Special Operations College of the People's Liberation Army in Beijing from Nov 23-27, the Defense Ministry said on Wednesday.

The participants exchanged experience on strengthening counter-terrorism capacity and cooperation.

The delegates also went to Kashgar, a city located in the southwestern part of the Xinjiang Uyghur autonomous region to watch the region’s special forces conduct counter-terrorism combat training on Monday.

China, Afghanistan, Pakistan and Tajikistan are members of a quadrilateral counter-terrorism mechanism established in August in response to the threat of terrorism and extremism.

The symposium is part of the four-nation mechanism scheduled work aiming to strengthen practical counter-terrorism cooperation and enhance their ability to jointly respond to threats of terrorism.
