The Russian invasion of Ukraine, a major exporter of grain, led to the blocking of all grain shipments until an agreement called the Black Sea Grain Initiative was signed in Istanbul between Ukraine, Russia and the UN. This agreement will expire on 19 November unless renewed. Renewal negotiations were being facilitated by the UN throughout October until the 29th, when a drone attack on Russian naval ships prompted Russia to suspend participation. Talks resumed on 2 November, with hopes to extend the agreement for a year. On 17 November Ukraine’s minister of infrastructure said the initiative would be prolonged, but only for 120 days.
