The Kremlin said on Friday that Russian President Vladimir Putin would decide what counter-sanctions to impose on Washington, a day after U.S. President Joe Biden hit Moscow with an array of punitive measures, but gave no indication of timing.

Axar.az reports citing foreign media that The U.S. government on Thursday blacklisted Russian companies, expelled Russian diplomats and barred U.S. banks from buying sovereign bonds from Russia's central bank, national wealth fund and Finance Ministry.

Kremlin spokesman Dmitry Peskov said Moscow was mulling its response.

"The principle of reciprocity for such matters has not been cancelled, but everything will depend on the decisions made by the (Russian) head of state."

Peskov did not say when Putin would decide on counter-sanctions, though Russia's Foreign Ministry said on Thursday retaliatory sanctions would come soon.
