China is to block all websites related to cryptocurrency trading and initial coin offerings (ICOs) - including foreign platforms - in a bid to finally quash the market completely.
"To prevent financial risks, China will step up measures to remove any onshore or offshore platforms related to virtual currency trading or ICOs," said an article published by Financial News, a publication affiliated to the People's Bank of China.
The article acknowledged that recent attempts to stamp out digital currencies by shutting down domestic exchanges had failed to completely eradicate trading.
"ICOs and virtual currency trading did not completely withdraw from China following the official ban ... after the closure of the domestic virtual currency exchanges, many people turned to overseas platforms to continue participating in virtual currency transactions.
"Overseas transactions and regulatory evasion have resumed ... risks are still there, fuelled by illegal issuance, and even fraud and pyramid selling," the article said.
