Ukraine has written to seven of the world’s largest cryptocurrency exchanges, asking them to block Russian users from accessing their platforms. The letter, dated March 15 and obtained by Bloomberg, was sent by Ukraine’s financial intelligence unit, known as NBU.

In addition to Binance and Coinbase, the other exchanges targeted by the request are Bitstamp, Bitfinex, Kraken, OKEx, Poloniex, and Yandex.Money.

According to the NBU, Russian nationals have been using these platforms to circumvent Ukrainian sanctions. “Russian citizens and companies are barred from transferring funds through Ukrainian banks,” reads the letter. “We believe that the use of cryptocurrencies by individuals and legal entities from Russia for cross-border transactions would breach the sanctions regime.”

The exchanges have not yet commented on the matter.

This is not the first time that Ukraine has taken measures to prevent Russian nationals from circumventing its sanctions. In February, the country’s central bank blocked access to more than two dozen Russian websites that were offering cryptocurrency-related services.
