Poland's foreign minister says the shape of the nation's democracy under the new right-wing government is better than some foreign commentators suggest and invited German politicians to visit and check.

Witold Waszczykowski spoke Monday after meeting with German Ambassador Rolf Nikel, whom he had summoned to protest "anti-Polish" statements by some German politicians.

Nikel said that Polish-German relations are a "treasure that should be protected."

On Sunday, European Parliament President Martin Schulz likened Poland's current politics to those of Russian President Vladimir Putin. Another member of Germany's Social Democratic Party, Volker Kauder, recently spoke in favor of sanctions against Poland.

The comments were in reaction to new legislation that Poland's ruling Law and Justice party adopted on a constitutional court and on state media.
