I keep expecting to see more of those last actions with the Chinese presence in Africa.
Chinese are patient. Avoid conflict until a few million more young Chinese males have moved in. Meanwhile, establish caches of arms and ammo.
When it's time, all they have to do is seize a seaport and an airport, and hold them for a couple of days as reinforcements arrive from China. Once a firm beachhead is established in Africa, the Chinese forces can expand from there quickly, using their huge fleet of container ships to transport men and material over.
