At the end of January 1942 eleven I-153s of the 17th Pursuit Squadron led by squadron commander Liu Qingguang, were quartered at Kunming (Yunnan Province). According to intentions, they were to repulse Japanese air attacks together with the American volunteers, who also were stationed there. However after some time they were sent on to Laxu airbase in Burma where they were utilised for communications and in May flew sorties attacking ground targets.
