At the height of China's command over the Bitcoin market a couple or more years ago the number of full nodes there regularly fell below 100.

I've just had a look and the number of full nodes has gone up hugely in the last few months to over 2000 now, in fact it's added over 1000 in the last month alone.

Can anyone in the know tell me why this has happened?
