Russian PM: US sanctions amount to ‘full-scale trade war’

Russian Prime Minister Dmitry Medvedev says new US sanctions against his country amount to a “full-scale trade war”.

Earlier, US President Donald Trump signed a law approving new measures against Russia as well as Iran and North Korea.

He has criticised the new bill as flawed and said he was forced to sign the law by Congress.
