NEW DELHI, Sept 9 (Reuters) - Turkish President Tayyip Erdogan held talks with Japanese Prime Minister Fumio Kishida at the G20 leaders' summit in New Delhi on reviving the Black Sea grain deal, two sources with knowledge of the matter told Reuters on Saturday.

Russia quit the deal in July - a year after it was brokered by the United Nations and Turkey - complaining that its own food and fertiliser exports faced obstacles and that not enough Ukrainian grain was going to countries in need.
