In a meeting with Iranian Ambassador to the Democratic Republic of Congo Hamid Reza Qomi in Kinshasa, Alexis Thambwe Mwamba also praised Tehran's resistance against the Western countries' pressures to curb Iran's peaceful nuclear program.
Washington and its Western allies accuse Iran of trying to develop nuclear weapons under the cover of a civilian nuclear program, while they have never presented any corroborative evidence to substantiate their allegations. Iran denies the charges and insists that its nuclear program is for peaceful purposes only.
Tehran stresses that the country has always pursued a civilian path to provide power to the growing number of Iranian population, whose fossil fuel would eventually run dry.
Elsewhere at the meeting, Mwamba welcomed an invitation letter from Iranian Foreign Minister Manouchehr Mottaki to pay a visit to Iran.
Congolese foreign minister and the Iranian ambassador also held talks on the recent events in the Gaza Strip and other regional and international issues.
Earlier, Iran's industries and mines minister and Congo's energy minister had signed a cooperation agreement.
As per the agreement, the two countries agreed to cooperate in the fields of technology, industry, infrastructure, energy, housing and urban development, economy, trade, mining and geology.
