Quoted by Reuters, Ryabkov said that "we will of course intensify work related to import substitution, reduction of dependence on U.S. payment systems, on the dollar as a settling currency and so on. It is becoming a vital need." The reason for that is that "the US is using its dominating role in the monetary and financial system to impose pressure on foreign business, including Russian companies."
As a reminder, three years ago the MasterCard payment system stopped serving clients of seven Russian banks without warning after Washington imposed its first set of sanctions on Moscow in 2014. In response, the Russian government ordered the creation of a national payment system. With the support of the country's banking system, the Mir charge card was introduced in 2015, although there is no information on what its adoption rate has been in the following years.
