LUANDA, June 26 (Reuters) - Russia and Angola vowed to work together in areas ranging from energy to mining and the telecommunications sectors in a bid to bolster ties between the former Cold War allies.

Russian President Dmitry Medvedev's visit to Angola, the first to the African nation by a Russian head of state, follows stops in Egypt, Nigeria and Namibia where he faces tough competition from China and the United States for resources.

Standing next to Angolan President Jose Eduardo dos Santos, Medvedev said Russian state-oil company Zarubezhneft and Angolan state-run oil firm Sonangol were in talks to explore for hydrocarbon deposits.
