Soldiers at the mine clearance headquarters of Yunnan's military region carried out leftover mine removal in the mine field near the No. 265 boundary monument during Spring Festival. Hundreds of thousands of cannonballs have been removed, some of which ceased to be effective and some of which were still lethal, Chinamil.com.cn reported.
The soldiers responsible for mine removal are stationed in Yunnan's Molipo County, close to Tianbao Port. In the 1990s, soldiers conducted the first mine clearance operation along the China-Vietnam border, and Tianbo Port was an important trade channel connecting China and Vietnam.
