The Russian leader is on his first sub-Saharan visit as head of state. He is being accompanied on his two-day visit by several ministers and a delegation of top Russian businessmen.
"The sides regard each other as friendly states and will develop partnership relations on the basis of common national interests, ideals of freedom, democracy, equality, commonly accepted principles and norms of international law, and in accordance with the goals and principles of the UN Charter," the treaty says.
According to the treaty, Russia and South Africa intend to maintain constant bilateral dialogue at a high political level, and to hold regular consultations at various levels.
The sides confirmed their obligations on the most important multilateral disarmament and non-proliferation agreements, and reasserted their readiness to strengthen the UN's peacekeeping potential.
"The sides will support mutual efforts aimed at developing cooperation with leading regional organizations, including the Commonwealth of Independent States and the Southern African Development Community," the document says.
Russia, as the Group of Eight industrialized nations' current chair nation, highlighted African development this year.
The two countries also emphasized the need to maximize bilateral trade possibilities.
Putin said Tuesday at a joint press conference with President Mbeki in Cape Town that one Russian company intends to invest more than $1 billion in South Africa's economy.
"One of our companies is planning to invest more than $1 billion in South Africa's economy, [namely] in manganese ores," he said.
Putin also said another company was ready to help South Africa develop electricity and build an aluminum plant.
Although South African companies, such as fruit producers and brewer SAB/Miller, which produces several popular brands of beer at a plant in central Russia, have made inroads into the Russian market, the Kremlin believes trade could be significantly increased from the 2005 figure of $171 million.
Russia and South Africa agreed to develop cooperation in the energy and transportation sectors, the defense and aerospace industry, the fishing industry, healthcare, culture, sports and tourism.
Speaking about cooperation in the energy sector, Putin said Russia will supply South Africa with nuclear fuel until 2010.
