Ten agencies, including the central bank, financial, securities and foreign exchange regulators, vowed to work together to root out "illegal" cryptocurrency activity, the first time the Beijing-based regulators have joined forces to explicitly ban all cryptocurrency-related activity.
China in May banned financial institutions and payment companies from providing services related to cryptocurrency transactions, and issued similar bans in 2013 and 2017.
The repeated prohibitions highlight the challenge of closing loopholes and identifying bitcoin-related transactions, though banks and payment firms say they support the effort.
Friday's statement is the most detailed and expansive yet from the country's main regulators, underscoring Beijing's commitment to suffocating the Chinese crypto market.
"In the history of crypto market regulation in China, this is the most direct, most comprehensive regulatory framework involving the largest number of ministries," said Winston Ma, NYU Law School adjunct professor.
