Those who have lived in Germany for many years should actively show a "high level of loyalty", the Chancellor said.
Chancellor Angela Merkel told Ruhr Nachrichten newspaper on Tuesday that people with Turkish roots living in Germany should be loyal to the country.
"We expect that people of Turkish origin who have been living in Germany for a long time should develop a high level of loyalty to our nation," Merkel said.
"Therefore we are trying to have open ears to hear their concerns and to understand them. And for this we are also keeping in close contact with immigrant associations."
