Poland's Prime Minister Donald Tusk criticised a decision by Germany to tighten controls on its land borders, calling on Tuesday for urgent consultations with other affected countries and more support for Warsaw's own immigration policies.
Relations between Poland and Germany have become warmer since Tusk's pro-European coalition came to power in December, but there is exasperation in Warsaw at Berlin's reluctance to commit to joint European Union financing for defence and strengthening the bloc's eastern border.
Poland has been facing what it says is a migrant crisis orchestrated by Belarus and Russia on its eastern border since 2021.
With Germany seeking to toughen its stance on immigration following a surge in arrivals, Berlin on Monday announced plans to impose tighter controls at all of the country's land borders, which would normally be part of the Schengen free-movement zone, for six months starting on Sept. 16.
"Such actions are unacceptable from the Polish point of view," Tusk told a meeting of Polish ambassadors in Warsaw.
"Today we need full support from Germany and the entire EU when it comes to help in organising, financing, arming the eastern border, also in the context of illegal migration."
He said that what Poland needed was not tighter controls on its border with Germany, but more engagement from Berlin and others in securing the EU's external border.
"In the coming hours we will contact other countries affected by Berlin's decisions for urgent consultations on action on the EU level," he said.
The German interior ministry did not immediately reply to an emailed request for comment.
Tusk said that the decision was a reaction to failed German policies on immigration from the past, not to failures from Poland's side.
Recent deadly knife attacks in Germany in which the suspects were asylum seekers have stoked concerns over immigration.
The Islamic State group claimed responsibility for a knife attack in the western city of Solingen that killed three people in August.
