Topping the list of foreign policy concerns were refugees, with 26 percent of respondents worried about Germany's ability to cope with inflows of asylum seekers.

Relations with President Trump and the United States ranked second, with 19 percent describing them as a major challenge, followed by Turkey at 17 percent, North Korea at 10 percent and Russia at 8 percent.

Since entering the White House in January, President Trump has unsettled Germans by pulling out of the Paris climate accord, refusing to certify an international agreement on Iran's nuclear programme and criticising Germany's trade surplus and its contributions to the NATO military alliance.

President Trump's actions prompted the usually cautious German Chancellor Angela Merkel to say earlier this year that Berlin may not be able to rely on the United States in the future. She also urged Europe to take its fate into its own hands.
