Russia's foreign ministry said on Monday that attempts by the West and the G7 group of nations in particular to isolate Moscow have worsened global food shortages.

G7 foreign ministers promised on Saturday to reinforce Russia's economic and political isolation, continue supplying weapons to Ukraine and work to ease food shortages stemming from Russia's Feb. 24 invasion of its neighbour.

"Attempts to divert Russia economically, financially, and logistically from long-standing channels of international cooperation are only exacerbating economic and food crises," the foreign ministry said in a statement on its website.

"It should be noted that it was the unilateral actions of Western countries, primarily from the Group of Seven, that exacerbated the problem of breaking the logistics and financial chains of food supplies to world markets."

Before the war, Ukraine and Russia combined accounted for about 29 percent of wheat production for the world market.

Moscow calls its actions in Ukraine a "special military operation" to disarm Ukraine and protect it from fascists. Ukraine and the West say the fascist allegation is baseless and that the war is an unprovoked act of aggression.
