German Foreign Minister Sigmar Gabriel told a news conference in Berlin his government had made a decision to take a new direction with its Turkey policy, after its attempts to resolve political disagreements with Ankara failed. In a press conference in Berlin, he said, "We have to be clearer than before, so the authorities in Ankara understand that their policies are not without consequences." .
The German government summoned Turkey's ambassador on Wednesday to demand the release of a jailed trainer of human rights activists, and said the foreign minister was interrupting his vacation for consultations on relations with Ankara.
Deniz Yucel, who works for the daily Die Welt, was arrested February 14 in Istanbul.
Turkish President Recep Tayyip Erdogan has repeatedly said the rights activists now arrested were involved in a meeting that had the "nature of a continuation" of the coup attempt.
Berlin on Wednesday summoned Turkey's ambassador over the detention of a German human rights activist and issued a fresh warning about the North Atlantic Treaty Organisation partner's respect for the rule of law.
The countries also have tangled over Turkey blocking German lawmakers' visits to German troops serving in the campaign against the Islamic State group at two Turkish air bases and over authorities' refusal to allow rallies by Turkish government politicians in Germany.
"It takes two to tango!" he said.
But he said its "poor human rights record" raised concerns about whether Germans should visit the country.
Earlier Wednesday, a newspaper publisher said it has filed an appeal to Turkey's highest court against the incarceration for the past five months of a German-Turkish reporter.More news: Billions of tons of plastic trash accumulating on Earth, says USA researchers

On Saturday (25 March) the House of Commons Foreign Affairs Committee issued a report on the UK's relations with Turkey, in which the Erdoğan government's claim that Gülenists masterminded the 15 July coup attempt is refuted.
"We need our policies towards Turkey to go in a new direction. we can't continue as we have done until now".
"I therefore cannot see how we, as the government, can still guarantee corporate investments in Turkey when we are seeing arbitrary, politically-motivated confiscations [of property] there and arbitrary deportations for political reasons", he underlined.
Mr. Gabriel broke off his holiday to return to Berlin and deal with the crisis after Turkey arrested six human rights activists including German national Peter Steudtner on accusations of terrorism, the latest in a series of diplomatic rows.
Steudtner "was no Turkey expert - he never wrote about Turkey, he had no contacts in the political establishment. and never appeared as a critic", Gabriel told reporters.
In its statement, Germany's BGA exporters association added that "we must expect significant declines in exports if the measures under consideration are implemented" but that would not pose a major problem for German foreign trade as a whole.
"Foreign ministry sites are not always informed in a timely manner about the detention of German citizens, and access to consular services is not always ensured", it added.
"The comments again show the double standards in their approach to the law of those who prevent terrorists being brought to justice while embracing members of terrorist groups which target our country", the ministry said.
Juergen Hardt, a senior member of Chancellor Angela Merkel's ruling conservative party, said the European Union candidate country had now "left the path to Europe".
