Kyiv-Warsaw talks continue in bid to resolve trade dispute

Ukraine’s agricultural minister, in a phone call with his Polish counterpart, has agreed to work out a solution to a trade dispute that is in the interests of both countries, the Ukrainian agriculture ministry said on Thursday.

A US official who recently visited Poland dismissed suggestions that Mateusz Morawiecki’s comments were a sign of cracks in Western solidarity with Ukraine.

The official, who spoke to Reuters on condition of anonymity about the Polish prime minister’s comments, said:

We’re all human and there are moments of tension... But that doesn’t mean that there’s going to be some dramatic shift in alliance unity or even Poland’s fundamental position and determination to support Ukraine for as long as it takes.
