MOSCOW (Reuters) -President Vladimir Putin said on Tuesday that Russia was considering withdrawing from the Black Sea grain deal because the West had cheated Moscow by implementing none of the promises to get Russian agricultural goods to world markets.

The deal allowing Ukraine to resume seaborne grain exports was brokered by the United Nations and Turkey in July last year to help tackle a global food crisis the U.N. said had been worsened by Europe's deadliest conflict since World War Two.

To convince Moscow to approve the pact, known by diplomats as the Black Sea Grain Initiative, a three-year accord was struck at the same time under which U.N. officials agreed to help Russia with its own food and fertilizer exports.

But Putin said that had not been implemented due to the perfidy of the West.

"We are thinking about getting out of this grain deal now," Putin told a meeting of Russian war correspondents and military bloggers.

"Unfortunately, we were once again cheated - nothing was done in terms of liberalising the supply of our grain to foreign markets. There were a lot of conditions that the Westerners had to fulfill under the leadership of the U.N.

"Nothing has been done," Putin added.

Western powers have imposed what they cast as the toughest sanctions ever on Russia over its full-scale war in Ukraine launched on Feb. 24, 2022.

While Russia's food and fertilizer exports are not sanctioned, the West's restrictions on payments, logistics and insurance pose barriers to shipments, according to Moscow and major Russian grain and fertiliser exporters.

Russia and Ukraine are two of the world's top agricultural producers, and major players in the wheat, barley, maize, rapeseed, rapeseed oil, sunflower seed and sunflower oil markets. Russia is also dominant in the fertiliser market.

DEMISE OF THE DEAL?

United Nations Secretary-General Antonio Guterres said on Monday he was concerned Russia would on July 17 quit the grain deal.

"...We are working hard in order to make sure that it will be possible to maintain the Black Sea initiative and at the same time that we are able to go on in our work to facilitate Russian exports," Guterres told reporters.

Putin made it absolutely clear that Russia is considering stopping participation in the grain deal.

He said he would discuss its future with some African leaders expected to visit Russia soon, adding that Moscow was ready to supply grain for free to the world's poorest countries.

"Almost nothing goes to African countries," Putin said of the current situation, adding that Moscow had agreed several times to extend the deal but had nothing to show for doing so.

The current deal will expire on July 17 unless Russia agrees to extend.

Russia's specific demands are that Russian Agricultural Bank (Rosselkhozbank) be reconnected to the SWIFT payment system, that supplies of agricultural machinery and parts to Russia needed to be resumed, and that restrictions on insurance and reinsurance needed to be lifted.

Other demands include the resumption of the Togliatti-Odesa ammonia pipeline that lets Russia pump the chemical to Ukraine's main Black Sea port, and the unblocking of assets and accounts of Russian companies involved in food and fertiliser exports.
