Moscow: Russian air defence systems manufacturer Almaz-Antei is in talks over setting up service centres in India, China, Vietnam, and Algeria, a company official said at the Oboronexpo 2014 arms exhibition Friday. "Service centres are an important guideline on which we`re actively working. We offer our partners to set up such centres," deputy head of the Almaz-Antei concern Vyacheslav Dzirkaln said. "It is a very effective method for operating equipment, allowing for quick decisions on modernization and repairs of air defence systems without moving them from country to country," he added.
