Iranian Foreign Minister Manouchehr Mottaki will visit Gabon, the Irna news agency reported.
Durin the visit, the minister will discuss bilateral relations and regional and international issues.
Mottaki stated that Gabon is the member of the U.N. Security Council, "and we want to express our position one more time on the need for a uranium exchange for the Tehran reactor."
In October 2009, the International Atomic Energy Agency (IAEA) and six international mediators on Iran - Russia, the United States, China, Britain, France and Germany - offered to exchange with Iran low-enriched uranium for high-enriched uranium. Iran has not rejected the proposal, but the parties failed to agree on a fuel exchange.
The United States and other Western countries accuse Iran of developing nuclear weapons for military purposes under the guise of a peaceful nuclear energy program. Tehran denies the charges, saying its nuclear program is aimed solely at meeting the country's electricity needs. The U.N. Security Council adopted five resolutions in connection with the suspension of Iran's nuclear program. Three involve the use of economic sanctions on Iran.
The Tehran laboratory reactor was built 40 years ago by the United States and its main function is to produce medicine.
The minister paid a one-day to Algeria March 31.
