A top official says Poland's new president will make his first foreign trip to the capital of Estonia on Sunday, followed by visits to Berlin and London.

Choosing one of the Baltic states for his first trip is consistent with President Andrzej Duda's plans to emphasize Poland's alliances with other countries in Central and Eastern Europe in hopes of becoming a stronger voice for a region that is nervous about Russia's resurgence.

Krzysztof Szczerski, Duda's foreign policy adviser, said Monday the president would visit Berlin on Aug. 28 for meetings with German Chancellor Angel Merkel and President Joachim Gauck, followed by a visit to London on Sept. 15.

The conservative party that backs Duda, Law and Justice, is sometimes skeptical of Germany's intentions toward Poland.
