Kyiv said Thursday it would hold talks with Warsaw in the coming days over an escalating dispute on Ukrainian grain exports, as the neighbors reiterated their "close" ties.

Poland -- which holds parliamentary elections next month -- has extended an embargo on Ukrainian grain, going against a European Commission decision to end the restrictions.

The issue has led to a diplomatic spat between the allies during the Russia-Ukraine war.

"The next negotiations will take place in the coming days, during which the issues prepared by both sides will be discussed," Kyiv's agriculture ministry said in a statement.

It said Ukrainian Agriculture Minister Mykola Solsky held a telephone conversation with his Polish counterpart Robert Telus.

"The ministers discussed the situation as well as Ukraine's proposal for its settlement, and agreed to find a solution that takes into account the interests of both countries," the statement read.

It added that "the parties confirmed the close and constructive relations."

Ukraine has filed a lawsuit at the World Trade Organisation against its three EU neighbors -- Poland, Slovakia and Hungary -- over the bans on Ukrainian grain.

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.
