Prime Minister Anastase Murekezi will attend the inauguration of Turkish President-elect Recep Tayyip Erdogan, who is due to be officially sworn in today after winning the country's first ever popular vote for head of state. He will be representing President Paul Kagame at the ceremony.
Mr Erdogan, who served three terms as prime minister, has vowed to give more power to the previously ceremonial post.
Outgoing Foreign Minister Ahmet Davutoglu is set to be PM after being elected head of the governing AK Party.
Under the constitution, Mr Erdogan must cut his ties to the AK Party once he becomes president.
At the party's congress on Wednesday he made his last speech as leader, saying: "What is changing today is the form, not the essence. The mission which our party has assumed, the spirit of its cause, its goals and ideals are not changing."
Mr Davutoglu will replace Mr Erdogan as prime minister.
