I think that literally the last thing the PRC needs to worry about is a land invasion. The US is their strongest rival, but it has 1/5 the population, and its technological edge is not what it once was. In some other thread, someone mentioned that US military doctrine is to not attack any defended position unless they have at least a 3 to 1 advantage. As long as the PRC stays militarily cohesive, any invading army is going to get annihilated. Plus the PRC has nukes, which is a further deterrent. IMHO, the PRC's (really the CCP's) biggest strategic threat is domestic, and they're starting to transition into a more imperialistic/expansionist mode to make good on revanchist sentiment.
