Beijing: Chinese and Pakistani forces on Sunday launched a joint air drill, a military spokesperson announced.
The Chinese contingent includes fighter jets, fighter bombers and early warning planes while Pakistan has dispatched fighter jets and early warning planes for the military exercise, Air Force spokesperson Shen Jinke said.
Shen, however, did not mention how long the drill would last, Xinhua news agency reported.
The joint exercise called "Shaheen (Eagle)-4" is part of a series of military exchange programmes between the two air forces, Shen said, adding that China's air force was willing to expand the scope of cooperation with various countries.
The first such drill was held in Pakistan in March 2011, the second in China's western Xinjiang Uygur region in September 2013.
The third was held in Pakistan's Punjab province in May 2014.
