The Chinese People’s Liberation Army (PLA)forces on Tuesday staged an air-ground live-fire drill in south China, close to the border with Myanmar, military sources said.

The joint drill, carried out by the Southern Theater Command of the PLA according to anannual training schedule, was aimed at testing the troops’ capabilities in rapid maneuver, precise destruction, vertical blockade and joint strike.

The live-fire drills of the People’s Liberation Army (PLA) in Southwest China’s YunnanProvince near the Myanmar border on Tuesday serves as a warning to both the Myanmar government and ethnic militias that their conflict should not cross over to China, Chinese experts said.

They coordinated closely and attacked targets precisely, the sources said. Under powerful fire support from air and ground, the armored infantry unit moved rapidly, forming a blockade of passage.

Colonel Fang Xin, who was with the the theater command, said the live-fire drill demonstrated the PLA’s resolve and will in safeguarding national security in border areaand air defense and protecting people’s safety and their property.

It also showed the PLA’s capability to win in these missions, Fang added.
