The ChineseSupply Depot remains the main structure used for harvesting and processing supplies scattered around the battlefields. While the design has changed over the years to a smaller, more streamlined structure, the purpose and functionality remain the same as they've always been.
Lays a minefield around the building that explodes when an enemy steps on it, causing 100 to 50 LAND_MINE damage over a radius of 5 to 10. Triggered mines are replaced after 20 seconds. Costs $400 and takes 12 seconds to complete.
The Supply Center is the same as those of other factions, and once it is constructed it automatically generates a Supply Truck, and is able to build more. Once Supply Trucks have harvested enough supplies they return to the Supply Center to deposit them, helping the Chinese economy.
