 A third ship from Ukraine-transited Istanbul's Bosphorus Strait on September 3 under a humanitarian corridor that Kiev announced after Russia pulled out of the Black Sea Grain Initiative in July. The Liberia-flagged Anitarisa transited the Bosphorus a day before Turkish President Tayyip Erdogan met with Russian President Vladimir Putin in Russia's Black Sea Resort of Sochi, as part of Ankara's efforts to convince Moscow to rejoin the deal. Russia has blockaded Ukrainian Black Sea ports since it invaded its neighbor in 2022 and threatened to treat all vessels as potential military targets after pulling out of the UN-backed deal in July. The deal had allowed Ukraine to export tens of millions of metric tons of produce.
