But German Foreign Ministry spokesman Martin Schaefer warned Turkey’s journey towards membership was long and complicated and said it was too early to predict the outcome of the talks.
He said: “Turkey’s membership of the European Union is a long process which we are in the middle of; the process is not simple, on the contrary, it is highly complicated due to a range of reasons.
“It is far too early to predict what the result at the end of this difficult accession process will be.”
Major stumbling blocks include Turkey’s refusal to recognise the Republic of Cyprus or Greece’s demands for an end to Turkish control in the island’s north.
There are also questions over whether Turkey can match EU standards on corruption, data protection, Europol, judicial co-operation and terror legislation.
