Iran's official IRNA news agency says the Indian prime minister has arrived in Tehran, the first such visit in over a decade.

The Sunday report said Prime Minister Narendra Modi will meet with President Hassan Rouhani and other Iranian leaders during his two-day visit.

The two countries are planning to develop Chabahar port in southeast Iran, expanding a trade route for the land-locked countries of central Asia that bypasses Pakistan.

India is also looking to import more oil from Iran and develop a gas field there. In 2012 Iran was India's second-largest crude supplier but oil exports subsequently fell.

Tehran has been seeking to reintegrate into the global economic system following a landmark deal with world powers that lifted sanctions in return for limiting its nuclear program.
