An unthinkable trip pre-Arab Spring.

CAIRO (AP) — Egypt’s President Mohammed Morsi will attend a summit in Iran later this month, a presidential official said on Saturday, the first such trip for an Egyptian leader since relations with Tehran deteriorated decades ago.

The visit could mark a thaw between the two countries after years of enmity, especially since Egypt signed its 1979 peace treaty with Israel and Iran underwent its Islamic revolution. Under Morsi’s predecessor Hosni Mubarak, Egypt, predominantly Sunni Muslim, sided with Saudi Arabia and other Sunni-dominated Arab states in trying to isolate Shiite-led Iran.

Until now, contacts have been channeled through interest sections, a low-level form of diplomatic representation. In May last year, Egypt, which was ruled by an interim military council, expelled a junior Iranian diplomat on suspicion he tried to set up spy rings in Egypt and the Gulf countries.

It’s too early to assess the implications of the visit or to what extent the Arab world’s most populous country may normalize relations with Tehran, but analysts believe it will bring Egypt back to the regional political stage. The visit is in line with popular sentiment since Mubarak’s ouster in an uprising last year for Cairo to craft a foreign policy independent of Western or oil Gulf countries’ agendas.

“This really signals the first response to a popular demand and a way to increase the margin of maneuver for Egyptian foreign policy in the region,” said political scientist Mustafa Kamel el-Sayyed. “Morsi’s visits … show that Egypt’s foreign policy is active again in the region.”

“This is a way also to tell Gulf countries that Egypt is not going to simply abide by their wishes and accept an inferior position,” he added.

The official said that Morsi will visit Tehran on Aug. 30 on his way back from China to attend the Non-Aligned Movement Summit, where Egypt will transfer the movement’s rotating leadership to Iran. He spoke on condition of anonymity because he was not yet authorized to make the announcement.
