A new financial order will be negotiated in the world, and the West won't have the main say in it anymore, ex-Russian President Dmitry Medvedev has claimed.

The "hellish" sanctions imposed on Russia by the US, EU, and their allies over the conflict in Ukraine have failed to cripple to the country, but are instead "returning to the West like a boomerang," Medvedev, the former Russian president who is now the deputy chairman of the Russian Security Council, wrote on Telegram. "This is hurtful for our 'friends' in Europe and overseas."
