The UN's humanitarian chief Martin Griffiths and Rebeca Grynspan, head of the UN's trade and development agency UNCTAD, will meet a high-level delegation from Moscow, led by Russian deputy foreign minister Sergei Vershinin.
"They will continue ongoing consultations in support of the efforts by the (UN) Secretary-General Antonio Guterres on the full implementation of the two agreements signed on July 22 in Istanbul," a UNCTAD spokeswoman told AFP on Thursday.
"It is hoped that the discussions will advance progress made in facilitating the unimpeded export of food and fertilisers originating from the Russian Federation to the global markets."
The 120-day Black Sea Grain Initiative, a UN-led deal agreed with Moscow and Kyiv, runs out on November 19.
The United Nations would like to renew the agreement for one year. Russia has yet to decide whether to extend the Black Sea agreements beyond November 19.
Russia is unhappy with some aspects of the arrangements and how they work, fueling doubt as to whether the Kremlin would want to carry on with the deal.
Moscow has complained its grain and fertilizer exports continue to face issues over sanctions imposed after its invasion of Ukraine, despite the Black Sea agreements that called for sanctions to spare agriculture-related products.
