As Turkish and Armenian leaders prepare to meet with U.S. President Barack Obama in Washington, Turkish Foreign Ministry Undersecretary Feridun Sinirlioglu is making the rounds in Armenia and Azerbaijan.

Prime Minister Recep Tayyip Erdogan sent Sinirlioglu as a special envoy to Baku on Friday to convey a letter to Azerbaijani President Ilham Aliyev. The Turkish diplomat previously held high-level talks in Yerevan on Wednesday.

Turkish Foreign Minister Ahmet Davutoglu confirmed that Turkey would continue its efforts to secure peace and stability for the Southern Caucasus in the light of the normalization protocols signed between Turkey and Armenia in October.

“We need to overcome the existing difficulties together in accordance with this vision,” Davutoğlu said Friday during a press conference with Greek Deputy Foreign Minister Dimitris Droutsas, Hurriyet reported.
