Russian Foreign Minister Sergei Lavrov on Friday threatened to abandon a landmark grain deal with Ukraine if obstacles to Moscow's exports remained.
Negotiated in July by Turkey and the United Nations, the agreement allows Ukraine -- one of the world's top grain producers -- to export grain through a safe corridor in the Black Sea.
"If there is no further progress in removing barriers to the export of Russian fertilisers and grain, we will think about whether this deal is necessary," Lavrov told a news conference in the Turkish capital Ankara, alongside his counterpart, Mevlut Cavusoglu.
The agreement has so far allowed the export of more than 27 million tonnes of grain and agricultural products.
