The issue has led to a diplomatic spat between the allies and prompted Kyiv to file a lawsuit against the three countries at the World Trade Organization (WTO).
Telus insisted that the Polish position on refusing Ukrainian grain imports remained “firm” and that the Ukrainian side “has accepted our reasoning”.
He reiterated Poland’s call for Kyiv to withdraw its WTO complaint but said that talks would continue “in the coming weeks”.
Poland will also study a Ukrainian proposal for part of the import checks to take place in German ports, rather than at the Polish-Ukrainian border, Telus said.
A Ukrainian press release said that agriculture ministers from Poland, Ukraine and Lithuania would meet in the coming days to discuss transferring grain quality checks to destination countries, to facilitate transit through Poland.
Warsaw holds parliamentary elections next month. Its populist right-wing government has strong support in agricultural regions and has presented the ban as protecting Polish farmers.
