I've taken the train across china from Hangzhou to Beijing and there is no lack of living space, or empty housing from the speculative bubble. The threat of south-irian is basically the classic yellow-peril threat model.
Its a really bad argument. As long as we are happy to export tertiary education and then proffer immigration channels, there is no basis to argue the Chinese polity wants to invade: it can get people here legally, for good benefit both sides.
Pleae, don't feed the racist troll. The chinese are not swamping us and they cannot cause earthquakes by jumping up and down at the same time.
