Amid the Ukraine crisis, Russian Ambassador to India Denis Alipov on March 02, while addressing a press conference said despite the sanctions imposed on Russia by western countries, supply of S-400 defence systems to India will not be affected. “Don't foresee any obstacles as far as S-400 supply to India is concerned; have routes to continue with this deal unobstructed. Sanctions - old or new, do not interfere in any way,” said Denis Alipov.
