Is Coinbase legal in China?

Could you please enlighten me on the legality of Coinbase in China? I've been hearing conflicting views on whether it's permissible to use this cryptocurrency exchange platform within the country. Given the increasing popularity of digital currencies, it's important for me to understand the regulatory framework surrounding it. Could you clarify if Coinbase is officially recognized and allowed to operate in China, or if there are any restrictions or regulations that users should be aware of? Thank you for your assistance in this matter.
