Russia will ban food imports from seven countries that have decided to support the European Union's (EU) sanctions against Moscow, the country's Deputy Prime Minister Arkady Dvorkovich said Tuesday.

"Our principle is that everybody who imposes sanctions on us will face retaliatory action," Dvorkovich told reporters.

The Russian government will introduce the ban in the near future, after discussing the details, Dvorkovich said without identifying the countries.

Montenegro, Albania, Iceland, Norway, Liechtenstein, Ukraine and Georgia have earlier confirmed to the EU their decisions to extend sanctions on Russia for a year.

Since last August, Russia has banned food imports from the EU, the United States, Canada and Australia, in retaliation for their anti-Russian sanctions introduced due to Russia's takeover of Crimea and its alleged role in the ongoing Ukraine crisis.
