Blockchain and bitcoin are two different things but isn't it that bitcoin made blockchain known for its use case? China is mostly being used by the manipulators and media to spread rumors where the majority reacts without any way of validating it.
Just like few years ago when it was reported that bitcoin was banned on China but the real thing it wasn't bitcoin but the ICOs. They have included bitcoin with the ban of ICO because it was a crypto and the reports said that crypto was banned in general. So, this is where the media played a big role to confuse everyone but as OP is pointing out, I think everybody knows it but we all agree that if there's no bitcoin, blockchain wouldn't be known. We will see how many companies will use blockchain technology without crypto in the future and how many of them will stay and rely on it meanwhile cryptocurrencies will emerge, keep going and is here to stay.
What is the point of your post? All cars need roads but not all roads need cars. Blockchain is a road and crypto is a car. Without crypto, the blockchain is useless so obviously china support crypto since that's the whole reason for the blockchain.
I think he's just pointing out that bitcoin and blockchain are not one. Blockchain can be used for other purpose not just for crypto nor bitcoin that's what he meant to say and thinks that everybody doesn't know about that
