China's government did more or less what Turkey's did. It regards Bitcoin and other cryptocurrencies as "investment alternatives" but not "currencies per se." In other words, one can be a "store of value" but not a "medium of exchange." The usual meaning of money is something that has both properties.
Wikipedia: "The main functions of money are distinguished as: a medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment. Any item or verifiable record that fulfils these functions can be considered as money."
China's government wants its yuan to have a monopoly on money.
