Following decades of stormy relations between Poland and Germany, the countries have developed a good friendship based on mutual understanding, said Polish President Andrzej Duda.

Duda met his German counterpart Joachim Gauck in Berlin on Sunday during commemorations marking the 25th anniversary of the signing of a treaty between Poland and Germany.

“Following decades of storms, following decades of drama, we are now seeing a decade of good friendship based on truth, based on partnership and mutual understanding,” Duda said.

“There is a good atmosphere between us […] there is still a friendship,” Germany’s Gauck said.

“A bridge was constructed between us, which we both probably did not expect,” he added.

In 2016, Warsaw and Berlin marked the 25th anniversary of the Polish-German Treaty of Good Neighbourship and Friendly Cooperation.

Signed in 1991, the treaty set Poland and Germany on a path of reconciliation, several decades after Nazi Germans inflicted mass destruction on Poland during World War II.
