Trust me, brand means a lot in China. It counts for far more than in most parts of the World. I expect the model 3 will be very popular in China, especially if it gets localised. Then it will receive the same generous incentives and reduced taxes, that domestic EVs receive.
On the whole, Chinese people buy Chinese cars, for 1 reason only, they can't afford a foreign brand. You wouldn't catch too many in the bigger cities, driving around in a blatant knock off, of a popular VW, Audi, BMW etc.
I am also suggesting, that Tesla will do just fine, in both China, and the rest of the World.
