Representatives of the Cabinet of Ministers of Ukraine arrived at the border with Poland to resolve the blockade, but Polish officials did not. The meeting did not take place.
"A month ago, we agreed that blocking the border harms our countries and that it is important to prevent such incidents. A month passed and we returned to this point again. Only now we see outright provocations."
