First, he was not the Finance minister, he was one of the deputy finance ministers, so he was in charge of just one sector, in his case Customs.
Second, his speech was something else altogether, he claimed that you can't fully ban them so you need to create options that would help the economy, what he is basically saying is that Chian should create their won coins controlled by the government to flood the markets and attract investors!
So, no, it's not about allowing Bitcoin and other decentralized coins, it's about issuing their own, which I start to think it is worse than a ban!
Make no mistake, he's the guy who was in charge of tariffs and was the planner for China's retaliations whenever there was a confrontation with the west, his views have nothing about freedom in it, it's just a reach for total control!
