I read something earlier that several Chinese exchanges are/will be trading bitcoin again. Their government is rumoured to be relaxing its ruling on the ban so this is probably the reason for the price increase we are currently witnessing.

Are you mean huobi they try open new site to avoid government ban by made new site huobi.pro

Yes it is, but you can try to see about the latest announcement that already released into the public by huobi itself, it seems the exchange will be actively trading the bitcoin again in the future. Some people are saying about the old news regarding the china ban was fake. But i don't know about the truth behind it.
What's your opinion?

Yes Huobi will be running again. there's been so much news saying that. I might feel strange if huobi try to create a new website to avoid the ban from the Chinese government, but it should be actionable by the government. I am more convinced that the government is actually just pretending to be about the ICO ban and trying to ban Bitcoin, whereas the fact that I am currently seeing that the government supports Bitcoin. I would probably be annoyed to hear that the Chinese government deliberately made a statement to make some parties get a profit when bitcoin prices decrease. this is a very dishonest act in my opinion.
