Qaddafi, who has ruled the oil and gas-rich African state since 1969, last visited the Russian capital in 1985, before the breakup of the Soviet Union.
Earlier in the day Mikhail Dmitriyev, head of the Federal Service for Military-Technical Cooperation, said that deliveries of Russian air defense systems, combat aircraft and warships would be among the key issues to be discussed during Qaddafi's visit to Moscow.
Libya was one of the key buyers of Soviet arms with estimated deliveries worth $20 billion. Moscow supplied Tripoli with about 300 combat aircraft, up to 4,000 tanks and dozens of air defense missile systems, as well as warships and small arms. Now the outdated equipment desperately needs modernizing.
According to open sources, Libya's armed forces are 90% equipped with Russian or Soviet weaponry.
After his visit to Russia, Qaddafi will pay an official visit to Kiev on November 4-6, the Ukrainian presidential press service announced on Friday.
