Is a food crisis coming for countries reliant on Ukrainian grain exports? The country’s government says that despite a grain export deal, Russia is blocking shipments of grain from Ukrainian ports in the Black Sea. Pavel Polityuk reports for Reuters:

Ukraineโ€™s ministry of renovation and infrastructure said on Thursday the U.N.-brokered Black Sea grain export deal had been halted again because Russia had blocked registration of ships to all Ukrainian ports.

A U.N. spokesman said Russia had informed officials overseeing the initiative that Moscow would limit registrations to the port of Pivdennyi, in Ukraineโ€™s Odesa province, until all parties agree to unblock the transit of Russian ammonia.

The United Nations and Turkey brokered theย Black Sea Grain Initiativeย between Moscow and Kyiv last July to help tackle a global food crisis aggravated by Russiaโ€™s invasion of Ukraine, a leading global grain exporter.

Russia agreed in May toย a two-month extensionย of the deal, which covers three Ukrainian ports including Pivdennyi, but has said the initiative will cease unless an agreement aimed at overcomingย obstaclesย to Russian grain and fertilizer exports is fulfilled.

โ€œThe Joint Coordination Centre in Istanbul (which oversees the initiative) has announced that it is impossible to draw up an inspection plan for June 1 due to another unjustified refusal of the Russian delegation to register the incoming fleet for participation in the Initiative,โ€ the Ukrainian ministry said on Facebook.

U.N. spokesman Stephane Dujarric said there had been a โ€œcontinuous slowdownโ€ in vessel departures under the Black Sea deal from April through May, and that the average daily inspection rate for ships had fallen to three.

โ€œThis is a very serious situation. We need to move forward,โ€ Dujarric told reporters at the U.N. in New York.

The Ukrainian ministry said Russia had registered only one incoming ship for inspection in the last two days of May and had given no explanation for the move, calling it a โ€œgross violationโ€ of the initiative.

Russia did not immediately comment on the ministryโ€™s statement.

Ukrainian officials have said that since mid-April, Russia has โ€œunreasonablyย restrictedโ€ the work of the Black Sea grain deal.

It said 50 vessels are waiting for inspection in Turkish territorial waters and that they were ready to deliver 2.4 million tonnes of Ukrainian food abroad. Some vessels had been waiting for inspections for more than 3 months.
