Russia agreed Wednesday to resume its participation in a deal brokered by Turkey and the UN to keep grain and other commodities moving out of Ukraine’s ports during Russia’s invasion of Ukraine. The renewed deal would prioritize shipments to African nations, including Somalia, Djibouti and Sudan, in line with Russia’s concerns that most of the grain exported since the agreement first was reached in July was ending up in richer nations. Russia had suspended its participation in the grain deal over the weekend, citing allegations of a Ukrainian drone attack against its Black Sea fleet.
