China’s approach to crypto regulation gained renewed attention after the Ministry of State Security (MSS) warned that crypto anonymity is not a reliable feature of digital assets. The intelligence and security agency said cryptocurrency transactions can be traced through blockchain records and related financial channels.
The MSS issued the warning via its social media platforms on Monday, highlighting the connection between virtual currencies and security concerns. The agency stated that blockchain networks preserve transaction histories. Meanwhile, crypto exchanges and payment systems can help identify users.

Meanwhile, the statement reinforced China’s existing position that cryptocurrency-related businesses remain illegal in mainland China. The latest remarks added a national-security focus to the country’s broader crypto-regulation framework.
The MSS statement centered on crypto anonymity and on authorities’ ability to trace digital asset activity. The agency described claims of complete anonymity as misleading, citing the permanence of blockchain records.
Additionally, the ministry said virtual currencies had been linked to money laundering activities and cyberattacks. It also stated that overseas intelligence groups could exploit claims of crypto anonymity to recruit individuals.
However, the warning did not introduce new restrictions on cryptocurrency activity. Instead, it reinforced existing crypto regulation measures by insisting on transaction transparency and blockchain records.
The MSS said cryptocurrency transactions could become identifiable through exchanges between digital assets, fiat currencies, and other payment systems. These connections can provide information about participants involved in crypto transactions.
China’s crypto regulation has continued through coordinated actions from financial and security agencies. In February, the People’s Bank of China and seven other government bodies issued a joint notice on virtual currency activities.
The agencies included the China Securities Regulatory Commission, the National Development and Reform Commission, and the Ministry of Public Security. The notice stated that speculative activity in virtual currency disrupted the economic and financial order.
Moreover, the February measures expanded regulatory attention toward tokenized real-world assets. The move showed that China’s oversight extended beyond traditional cryptocurrency activities.
The latest MSS warning followed these regulatory steps by focusing on security-related concerns. The agency linked virtual currency activity to risks of cybercrime, money laundering, and espionage.
Additionally, China’s crypto regulation previously targeted initial coin offerings and cryptocurrency exchanges. Authorities banned initial coin offerings and ordered domestic exchanges to close in 2017.
China strengthened its crypto regulation measures in 2021 by banning Bitcoin mining operations nationwide. Authorities later classified cryptocurrency-related businesses as illegal within mainland China.
China has maintained these restrictions, while Hong Kong has created a separate framework for virtual asset companies. Hong Kong received approval in 2022 to attract cryptocurrency businesses under its own regulatory system.
However, mainland China has continued to limit cryptocurrency trading and related business activities. The country’s policy has focused on controlling domestic virtual asset operations.
Andrew Fei, a partner at King & Wood in Hong Kong, said the MSS warning reinforced the prohibition on virtual currency trading in mainland China. He also noted that governments globally continue examining risks linked to digital assets.
The MSS statement further emphasized that crypto transactions create records that can be used to support tracking efforts. The agency’s comments reflected China’s continued focus on crypto regulation and the traceability of blockchain-based transactions.
