Americans are afraid of being invaded by Chinese army, while completely omitting the fact that both Chinese police and 3 letter services have few times bigger budgets (literally, MPS has around 3 times bigger budget than regular land forces,) more men, better training (armed police officers don't spend 50% of their time reading Marx, unlike army officers,) and, in some times, better equipment including heavy weaponry (in China, armed police forces, and "men in black" each have few armoured divisions, and are rumoured to have own heli force)

So, in the end, if West is to be afraid of Chinese invasion, they should be afraid of Chinese armed police, not the regular army.
