Moscow, November 30 (KCNA) -- Dmitri Medvedev, Russian president, recently called for modernizing the national defense industrial complexes.

Only when we refit the factories related to national defence industrial complexes is it possible to build new armed forces by 2020 and fulfill the task of supplying modern military technical equipment of high efficiency to the army, he said.

We have to start the work for this as soon as possible, he urged.
