Just like you said it is difficult to read the mind of the Chinese government as it has to do with cryptocurrency but I think they are gradually closing up the gap after they made the statement of banning btc and ICO in their country in 2017.
I think is not about the Chinese government per se, maybe those rich Chinese investors have a lot of extra money and where do they gonna put it? Of course the one that they love the most which is Bitcoin. Or maybe most of them are really hedging because of the US-China trade talks which is going to extend in April. So let's see how it goes. It's a smart move by the way, but we all know the Chinese government doesn't want to see this so it's gonna be interesting what they are going to do if they read this news.
