German Chancellor Angela Merkel met with French President Francois Hollande in Strasbourg on Sunday to discuss the current risks posed to unity in the European Union.
Diplomatic officials in Paris said that the ongoing refugee crisis and the threat it poses to the bloc's passport-free Schengen zone were high on the agenda, as well as Britain's EU membership, which hangs in the balance ahead of an upcoming in-out referendum.
Following bilateral talks in the French city, Merkel and Hollande are scheduled to join European Parliament President Martin Schulz for informal talks over wine and dinner.
No statements to the press are planned.
The talks precede Merkel's Monday visit to Ankara, when she plans to discuss multilateral plans to stem the flow of migrants to Europe with Turkish Prime Minister Ahmet Davutoglu.
