Russian President Dmitry Medvedev will receive Chavez later on Tuesday. Russian Prime Minister Vladimir Putin is also expected to meet with the Venezuelan leader.
Upon his arrival in Moscow, Chavez called for Russia and Venezuela to become strategic partners in oil and defense, something he said would "guarantee Venezuela's sovereignty, which is currently being threatened by the United States."
Ahead of his two-day visit, Chavez thanked Moscow for its recent support, including the provision of loans for the modernization of Venezuela's armed forces.
He also pledged to develop further bilateral cooperation with Moscow, saying that
Venezuela would continue to buy Russian military hardware, including combat aircraft and helicopters.
The Spanish news agency Efe said the potential acquisition of tanks by Venezuela could be discussed during the talks.
The Venezuelan leader will also hold a meeting with officials from the Il aircraft manufacturer, and defense contracts are also expected to be signed.
"I hope we will sign a number of contracts we have been working on over the past few years, including in the energy sphere and on defense cooperation," the Venezuelan leader said.
Chavez also plans to discuss the establishment of a Russian-Venezuelan bank to finance joint projects. The Venezuelan government has already made amendments to the law on the Central Bank for the purpose.
The Prensa Latina news agency quoted Venezuelan Foreign Minister Nicolas Maduro as saying that the Caracas-Moscow partnership was significant for the whole of South America, not just Venezuela.
Venezuela has bought over 50 combat helicopters, 24 Su-30MK2 fighters, and 100,000 Ak-103 rifles from Russia. It also holds a license for the production of the aforementioned military hardware. Moscow plans to start supplying Venezuela with Mi-28N helicopters in the latter half of 2009. The two countries have also negotiated the delivery of Russian diesel submarines to Caracas.
