He said this in an interview with the Delovaya Stolitsa (Business Capital) newspaper.
"As for personae non gratae, the beginning of this story was laid by the Ukrainian side. A year ago, the mayor of the Polish city of Przemysl, Robert Choma, was not allowed to enter Ukraine. Then the same story happened with a Polish professor from Lublin. Then there was a reaction from the Polish side, and [Secretary of the State Interagency Commission for the Commemoration of ATO Participants, Victims of War and Political Repressions] Sviatoslav Sheremeta was refused entry to Poland," Pieklo said.
In his opinion, it would be better for the two states to create a transparent system through which they would directly communicate and discuss the desirability of a certain citizen staying in a country.
"Such cases, as with the Przemysl mayor, the Polish professor, Sheremeta, benefit only those marginal elements who want to spoil relations between Poland and Ukraine," the ambassador said.
