China has long history of using light tanks – many of which have been discarded. Light tanks have become rarer as people have discovered that they need the same crew as a main battle tank, while offering said crew less protection.
China's primary light tanks have been the Type 62 light tank and the Type 63 amphibious light tank. Both feature 85mm main guns (the Soviet/Russian T-34 used a main gun of this caliber as well), and each hold 47 rounds for that gun. But like many light tanks today, they are light in the protection department.
The Type 62 has about two inches of armor at most.

China has now pushed the light tank to the VT-5. This is a much more powerful system. It is centered on a 105mm rifled gun with up to 38 rounds. This gun is pretty much what was used on the early models of the M1 Abrams, and prior to that, on the M60 Patton main battle tanks. ArmyRecognition.com notes that this tank will weigh between 33 and 36 tons. Secondary armament is a 12.7mm heavy machine gun and a 40mm automatic grenade launcher.
The last light tank in United States service was the M551 Sheridan. This vehicle saw action in the Vietnam War, Operation Just Cause, and Desert Storm before being retired in the mid-1990s. Called the Buford by some sources, the Army had the XM8 Armored Gun System ready to roll out, but it was cancelled as well.
Today, the United States Army uses the M1128 Stryker Mobile Gun System. It has the same 105mm rifled gun as the VT-5, but only holds 18 rounds.

Below, you can see video of the VT-5 as it is put through some live-fire paces in Inner Mongolia. A number of military attaches witnessed this performance. Did China build the light tank that units like the 82nd Airborne Division need?
