The United States on Thursday sought to facilitate Russian food and fertilizer exports by reassuring banks, shipping and insurance companies that such transactions would not breach Washington’s sanctions on Moscow over its invasion of Ukraine.

Enabling those Russian exports is a key part of attempts by the United Nations and Turkish officials to broker a package deal with Moscow that would also allow for shipments of Ukraine grain from the Black Sea port of Odessa, which have been blockaded by the war.

The written U.S. clarification came a day after Russia, Ukraine, Turkey and U.N. officials met in Istanbul for talks aimed at resuming Ukraine’s grain exports. Turkey announced that the parties would return next week to sign a deal.

"The United States strongly supports efforts by the United Nations to bring both Ukrainian and Russian grain to world markets and to reduce the impact of Russia's unprovoked war on Ukraine on global food supplies and prices," said the U.S. Treasury Department in the factsheet.

The war in Ukraine has sent prices soaring for grains, cooking oils, fuel and fertilizer, stoking a global food crisis.

Eduard Zernin, head of the Russian Union of Grain Exporters, described the U.S. move as "an act of goodwill" and a "real step in the fight against world hunger."

"We sincerely hope that other countries involved will follow this example and issue the necessary clarifications and licenses in order to remove hidden sanctions that hinder the supply of grain to countries in need," he told Reuters.

Key suppliers

Russia’s Feb. 24 invasion and blockade of Ukraine’s ports has stalled exports, leaving dozens of ships stranded and about 22 million tons of grain stuck in silos in Ukraine.

Moscow has denied responsibility for worsening the food crisis, blaming instead a chilling effect from Western sanctions for slowing its own food and fertilizer exports and Ukraine for mining its Black Sea ports.

Ukraine and Russia are major global wheat suppliers, and Russia is also a large fertilizer exporter, while Ukraine is a significant producer of corn and sunflower oil.

The U.S. Treasury made clear that the sale and transport of agricultural commodities, as well as medicine and medical devices, was allowed and would not be breaching a raft of sanctions that Washington has imposed on Russia.

Washington also stressed that there were no sanctions on Russia’s production, manufacturing, sale, or transport of agricultural commodities, including fertilizer, and that providing insurance or reinsurance for the transportation or shipping of those products was not prohibited.

Imports of Russian fish and seafood to the United States are banned under Washington’s sanctions.

As the U.N.-led talks got underway in May to revive Ukraine and Russian food exports, U.S. Ambassador to the U.N. Linda Thomas-Greenfield had said Washington was prepared to give written assurances – known as "comfort letters" – to shipping and insurance companies in relation to Russian exports.
