The relevant decree was signed by Russian President Vladimir Putin.
"The decree comes into force upon its singing," reads the document published on the official portal of the legal information of the Russian Federation.
Earlier, Putin said that the issue of countersanctions would be decided depending on relations with the partners.
As reported, August 6, 2014, Russian President Vladimir Putin signed the decree banning the imports of products from the United States, the countries of the European Union, Canada, Australia and Norway. Thus, Moscow responded to the sanctions imposed on it after the annexation of Crimea and Russia's interference in the conflict in eastern Ukraine. Several more countries were added to the decree later.
