"Complex issue.

You know, potash and mineral fertilizers, grain, the possibility of exporting Ukrainian grain are a complex tangle of issues that are currently being considered, ”RIA Novosti quoted Pankin as saying.

He noted that this issue "is not discussed at the UN level, it is discussed with us."

Earlier, US Permanent Representative to the UN Linda Thomas-Greenfield spoke about discussions about the possibility of exporting Ukrainian grain through safe corridors in the Black Sea.

In turn, the Kremlin reminded that before opening Ukrainian ports, including for the export of grain, they need to be cleared of mines, because the danger to shipping remains.
