Greek President Prokopis Pavlopoulos is on a two-day visit to Bulgaria to meet state officials and businesses.
On Monday he is to have a closed-doors meeting with Bulgarian counterpart Rosen Plevneliev and will later talk with Prime Minister Boyko Borisov and Parliament Speaker Tsetska Tsacheva, the Bulgarian Presidency's press office has said.
A meeting between Pavlopoulos and Bulgarian Patriarch Neofit I has also been scheduled, amid tensions between the Ecumenical Patriarch in Istanbul (often accused of serving the Greek church's interests) and the Bulgarian Orthodox Church.
On Tuesday, Plevneliev and Pavlopoulos are to meet with members of Bulgarian and Greek businesses.
The Greek President is coming at the invitation of Bulgaria's head of state.
