BERLIN, Oct. 19 (Xinhua) -- German Chancellor Angela Merkel will travel to Istanbul, Turkey, on Oct. 27 for a summit with the presidents of France, Russia and Turkey on Syria issues, a government spokeswoman said Friday.

The spokeswoman said the meeting will focus on the situation in the Idlib Governorate in Syria, and supporting for the implementation of the Russian-Turkish Sochi agreement, which vowed to build a demilitarized zone in the war-torn Syrian province.

In addition, the further progress of the political process in Syria under the leadership of the UN will be discussed, in particular the work of the Constitutional Commission, the spokeswoman said.

"The Federal Government views Russia, an ally of the Assad regime as a partner with a special responsibility," the deputy spokeswoman for German government Martina Fietz said at a regular press conference.

"At the same time, with its Sochi agreement with Russia, Turkey has also taken on a very special responsibility," said Fietz.
