The Group of 20 major economies plan to agree on compiling additional steps by 2021 against money laundering and funding of terrorist groups through the use of crypto-assets, sources close to the matter said Saturday.

The G20 finance ministers and central bank governors are set to urge the Financial Action Task Force (FATF), an international body, to devise new measures to prevent the malicious use of cryptocurrency and other advanced technologies when they gather in the city of Fukuoka for a two-day meeting from June 8, the sources said.

The chiefs are also expected to formally agree on strengthening regulations on cryptocurrency exchange operators such as requiring government registration.
