Four-way talks on grain deal set for May 10-11 in Istanbul - RIA

A high-level four-way meeting on the Black Sea grain deal will take place in Istanbul on May 10-11, the state-owned RIA news agency quoted Russian Deputy Foreign Minister Sergei Vershinin as saying on Tuesday.

Moscow has said it will not extend the pact - which allows for the export of grain from Ukrainian ports - beyond its expiration date on May 18 unless a list of demands is met to remove obstacles to Russia's own grain and fertilizer exports.
