ISTANBUL (AP) — Russia and Ukraine signed separate agreements Friday with Turkey and the United Nations clearing the way for the export of millions of tons of desperately needed Ukrainian grain — as well as some Russian grain and fertilizer — across the Black Sea. The long-sought deal ends a wartime standoff that has threatened food security around the globe.

The U.N. plan will enable Ukraine — one of the world’s key breadbaskets — to export 22 million tons of grain and other agricultural goods that have been stuck in Black Sea ports due to Russia’s invasion. U.N. Secretary General Antonio Guterres called it “a beacon of hope” for millions of hungry people who have faced huge increases in the price of food.

“A deal that allows grain to leave Black Sea ports is nothing short of lifesaving for people across the world who are struggling to feed their families,” said Red Cross Director-General Robert Mardini. He noted that over the past six months, prices for food have risen 187% in Sudan, 86% in Syria and 60% in Yemen, just to name a few countries.

Russian Defense Minister Sergei Shoigu and Ukrainian Infrastructure Minister Oleksandr Kubrakov signed separate, identical deals Friday with Guterres and Turkish Defense Minister Hulusi Akar at a ceremony in Istanbul that was witnessed by Turkish President Recep Tayyip Erdogan. Russia and Ukraine would not sign any deal directly with each other.

“Today, there is a beacon on the Black Sea,” Guterres said. “A beacon of hope, a beacon of possibility, a beacon of relief in a world that needs it more than ever.”

“You have overcome obstacles and put aside differences to pave the way for an initiative that will serve the common interests of all,” he told the envoys.

Guterres described the deal as an unprecedented agreement between two parties engaged in a bloody conflict. Erdogan hoped it would be “a new turning point that will revive hopes for peace.”

Yet in Kyiv, Ukrainian Foreign Minister Dmytro Kuleba sounded a more somber note.

“I’m not opening a bottle of champagne because of this deal,” Kuleba told The Associated Press. “I will keep my fingers crossed that this will work, that ships will carry grain to world markets and prices will go down and people will have food to eat. But I’m very cautious because I have no trust in Russia.”

The European Union and the U.K. immediately welcomed the news.

“This is a critical step forward in efforts to overcome the global food insecurity caused by Russia’s aggression against Ukraine,” said EU foreign policy chief Josep Borrell.

British Foreign Secretary Liz Truss applauded Turkey and the U.N. for brokering the agreement.

“We will be watching to ensure Russia’s actions match its words,” Truss said. “To enable a lasting return to global security and economic stability, (Russian President Vladimir) Putin must end the war and withdraw from Ukraine.”

African leaders also welcomed the deal, with South African President Cyril Ramaphosa saying “it has taken much too long.”

Ukraine is one of the world’s largest exporters of wheat, corn and sunflower oil, but Russia’s invasion of the country and naval blockade of its ports have halted shipments. Some Ukrainian grain is being transported through Europe by rail, road and river, but the prices of vital commodities like wheat and barley have soared during the war.

Although international sanctions against Russia did not target food exports, the war has disrupted shipments of Russian products because shipping and insurance companies did not want to deal with Russia.

Guterres said the plan, known as the Black Sea Initiative, opens a path for significant volumes of commercial food exports from three key Ukrainian ports: Odesa, Chernomorsk and Yuzhny.

The agreement, obtained by the AP, says a joint coordination center will be set up in Istanbul staffed by officials from Ukraine, Russia, Turkey and the U.N. to run the plan, including scheduling cargo ships’ arrivals and departures. The center will be headed by a U.N. official.

Inspection teams with representatives from all parties in Turkey will search vessels entering and leaving Ukrainian ports to ensure there are no weapons or soldiers on board. Inspections will take place at the entry and exit of the Bosporus.

Under the deal, “all activities in Ukrainian territorial waters will be under authority and responsibility of Ukraine,” and the parties agree not to carry out attacks against vessels and port facilities in the initiative. If demining is required to make the shipping lanes safe, a minesweeper from another country could clear the approaches to Ukrainian ports.

The sides will monitor the movement of ships remotely and no military ships. aircraft or drones will be allowed to approach “the maritime humanitarian corridor” closer than a distance set by the center. The agreement will remain in effect for 120 days and can be extended automatically.

A senior U.N. official said it will take a few weeks before the deal is fully working, adding that Ukraine needs about 10 days to get the ports ready and also needs time to “identify and be clear about those safe corridors.” The aim is to export 5 million tons of grains per month to empty Ukraine’s silos in time for this year’s harvest.

Guterres first raised the critical need to get Ukraine’s agricultural production and Russia’s grain and fertilizer back into world markets in late April during meetings with Putin in Moscow and Ukrainian President Volodymyr Zelenskyy in Kyiv. He proposed a deal in early June amid fears that the war could worsen hunger for up to 181 million people.

Peter Meyer, head of grain and oilseed analytics at S&P Global Platts, said the deal does not “mean that the global supply crisis is over.’’

Traders anticipated a deal for the past several weeks, he said, so its effect might already have shown up in grain prices. And the agreement only covers the 2021 crop. There’s still considerable uncertainty about Ukrainian production this year and even next, Meyer said.

Before the deal, Russian and Ukrainian officials blamed each other for the blocked grain shipments. Moscow accused Ukraine of failing to remove sea mines at the ports and insisted on checking incoming ships for weapons.

Ukraine argued that Russia’s port blockade and launching of missiles from the Black Sea made any safe sea shipments impossible. It sought international guarantees that the Kremlin wouldn’t use the safe corridors to attack Odesa and accused Russia of stealing grain from eastern Ukraine and deliberately setting Ukrainian fields on fire.

Volodymyr Sidenko, an expert with the Kyiv-based Razumkov Center think tank, said Ukraine apparently did not raise the issue of stolen grain in the talks.

“It was part of a deal: Kyiv doesn’t raise the issue of stolen grain and Moscow doesn’t insist on checking Ukrainian ships. Kyiv and Moscow were forced to make a deal and compromise,” he said.

The deal was also important for Russia’s geopolitical relations, the analyst noted.

“Russia decided not to fuel a new crisis in Africa and provoke a hunger and government changes there,” Sidenko said. “The African Union had asked Putin to quickly ease the crisis with grain supplies.”
