The Central Bank of Russia announces retaliation for freezing foreign assets.
"In response to the freezing of part of Russia's foreign exchange reserves, Russia has also introduced restrictions on the movement of funds that could be transferred to unfriendly countries in comparable amounts," she said in Moscow on Friday.
After Russian troops invaded Ukraine a month ago, the western states imposed sanctions, which is why Russia currently has no access to foreign exchange reserves worth 300 billion dollars.
The central bank also stated that all gold from domestic foreign exchange reserves is currently on Russian territory.
British Prime Minister Boris Johnson had previously raised access restrictions to Russia's gold reserves as a further means of exerting pressure.
It must be examined whether access to the gold reserves can be restricted in addition to measures on cash, Johnson told radio station LBC on Thursday.
"The more pressure we put on now, especially over things like gold, the more I think we can shorten the war."
The retaliatory measures follow a series of economic measures that Russia has announced in recent days.
Among other things, gas deliveries abroad should only be allowed to be paid for in rubles.
Furthermore, the central bank allows companies to pay debts actually denominated in foreign currency in rubles.
Analysts had speculated that Russia would soon default.
