BRUSSELS, March 21 - The European Commission, the executive arm of the European Union, is proposing to member countries to impose tariffs on grain imports from Russia and Belarus, commission President Ursula von der Leyen said Thursday.

Speaking at the end of the opening day of a summit of EU leaders in Brussels, Von der Leyen said the move would prevent Russia from destabilizing the EU market with its imports of cereals, oilseeds and derived products, The Associated Press reported.
