Excerpt taken from news.bitcoin.com:
The Group of Seven (G7) countries issued a joint statement stating that they “will ensure that the Russian state and elites, proxies and oligarchs cannot leverage digital assets as a means of evading or offsetting the impact of international sanctions.” Meanwhile, the U.S. Treasury Department is “closely monitoring any efforts to circumvent or violate Russia-related sanctions, including through the use of virtual currency.”
The G7 joint statement details:
"Specifically, in addition to other measures planned to prevent evasion, we will ensure that the Russian state and elites, proxies and oligarchs cannot leverage digital assets as a means of evading or offsetting the impact of international sanctions."
It has been a concern whether Russia can escape its sanctions using decentralized crypto. Coinbase started blocking wallets who belongs to Russian users, Binance stance is still to not freeze wallets. SKorea also started to take account to prevent Russian's in accessing their crypto wallets. Singapore also did the same earlier this month.
