Mahmoud Ahmadinejad, the president of Iran, has become the first leader of the Islamic Republic to visit Cairo since the 1979 Islamic revolution, arriving in the Egyptian capital on Tuesday.
Egypt's Islamist President Mohamed Morsi welcomed Mr Ahmadinejad at Cairo airport as he disembarked from the plane, television footage showed.
Mr Ahmadinejad, who is on a three-day visit, will attend an Organisation of Islamic Cooperation conference in Cairo and will hold talks with Egyptian officials, Iranian media said ahead of the trip.
Before leaving Tehran, Mr Ahmadinejad told reporters that during his visit he would work towards strengthening bilateral ties with Cairo.
"I will try to pave the ground for developing cooperation between Iran and Egypt," he was quoted as saying by Iran's official IRNA news agency. Without elaborating, he said the visit would "definitely influence the bilateral ties" between Tehran and Cairo.
