The soldiers fled with their arms from Paletwa town in the Chin State of Myanmar after their camps were overrun by the armed resistance group known as the People's Defense Force (PDF).
The Chinese nationals were taken into custody and then deported from the northern Shan state of Myanmar over the course of three months, from early September to mid-December.
President Myint Swe has warned Myanmar would "split into various parts" if the government "did not effectively manage the incidents happening in the border region".
