The news conference was held at the Sixth Armored Division of the Beijing Military Command in the northern Beijing suburbs as the PLA marked its 81st anniversary.

More than 100 journalists, including 48 foreign reporters, visited the division, one of China's elite land forces, on Friday morning.

This is the first time the Defense Ministry was holding a news conference in the barracks.
