BEIJING - The Chinese and Thai air forces will this month hold their first joint exercises, China's Defense Ministry said on Wednesday, in another sign of army-led Thailand's increased engagement with Beijing. The 'Falcon Strike 2015' drills will take place at the Korat Royal Thai Air Force Base from November 12-30, China's Defense Ministry said. 'The aim of this joint exercise is to increase mutual learning and understanding between the two countries' air forces, deepen Sino-Thai practical cooperation and increase mutual trust and friendship,' it said, without elaborating.
