(Bloomberg) -- The Kremlin confirmed that Russian President Vladimir Putin and Turkish counterpart Recep Tayyip Erdogan will meet in Sochi, southern Russia, on Monday. The pair are expected to discuss reviving the Black Sea grain deal after Moscow abandoned the agreement - brokered a year earlier by Turkey and the UN - in July. Russian officials have said repeatedly that not enough’s been done to address their demands, and Moscow has bombarded Ukrainian grain infrastructure in the past month. Er
