Ankara, Dec 12 : Presidents of Turkey and Ukraine have discussed expanding the scope of the grain deal and the Ukraine-Russia conflict over the phone, the Turkish presidency said in a statement. Turkish President Recep Tayyip Erdogan told his Ukrainian counterpart Volodymyr Zelensky on Sunday that Turkey continued to work towards meeting the humanitarian needs of the Ukrainian people in the "difficult winter months". "The grain corridor could be expanded to include different food products and other commodities," said Erdogan. He also expressed hope for "approaching a solution" to the issue of the Zaporizhzhia nuclear power plant in southern Ukraine, the statement said as quoted by Xinhua news agency report. Turkey has been evaluating the contributions that can be made for the implementation of the peace plan announced by Zelensky at the G20 Summit, the Turkish President told his Ukrainian counterpart.
