Foreign Minister Mohammad Javad Zarif will set off for West Africa on a four-nation tour to discuss possible ways of improving relations.

According to Press TV, Zarif will leave Tehran on Sunday at the head of a politico-economic delegation for a six-day visit.

He plans to hold talks with senior officials, including presidents, parliament speakers and foreign ministers, of Nigeria, Ghana, Guinea-Conakry and Mali.

The minister will wrap up his visit to West Africa on Friday.

Zarif has already paid two official visits to Africa.

He visited four East African countries - Kenya, Uganda, Burundi, and Tanzania – in February 2015, marking the beginning of a new chapter in Tehran’s ties with Africa.

The foreign minister also made a visit to North African countries of Tunisia and Algeria in August 2015.
