Russia faces a “major challenge” from sanctions denying access to foreign technology, President Vladimir Putin said Monday.

But Putin told his Council for Strategic Development that his country will not “lose heart” or see decades of progress reversed. Putin called for expansion of the technological capacities, research and  innovation of Russian companies. 

Russia has struggled to keep commercial airplanes maintained, and defense experts say Russia’s military has been forced to use legacy military hardware while trying to replenish its more modern weapons systems. 

“Obviously, we cannot develop in isolation from the rest of the world. And we won’t,” Putin said in a report posted in state-run Tass. “It is impossible in the present-day world to merely issue a decree and erect a huge fence. It is simply impossible.”
