New information from Myanmar suggests increasing military ties between China and Myanmar's largest ethnic insurgency, the United Wa State Army. The Chinese government will provide "aviation training" for 30 UWSA militants in China, according to an Irrawaddy newspaper source. This follows an IHS Jane's report from April 2013 that said China sent Mil Mi-17 helicopters to the UWSA. If true, this could suggest a beefing up of UWSA military capabilities and a renewal of Beijing's push to establish an ethnic buffer against Myanmar . Naypyidaw is trying to control its numerous ethnic insurgencies and the UWSA wants to use Chinese support as leverage for continued concessions . Based in Myanmar's northeastern Shan state, the ethnic Wa fighters who comprise the UWSA were the rank-and-file of the Chinese proxy insurgent group the Communist Party of Burma.
