REPUBLIKA.CO.ID, MOSCOW -- The United States has declared a full-scale trade war against Russia with the enactment of a new sanctions bill on Wednesday, said Russian Prime Minister Dmitry Medvedev.

"The hope of improving our relations with the new U.S. administration has come to an end," said Medvedev on Facebook, commenting on the signing of the bill by U.S. President Donald Trump.

The bill was approved overwhelmingly early this month by the U.S. Congress despite the Trump administration calling on lawmakers to grant the White House "flexibility" in dealing with Russia.

The Trump administration demonstrated "complete impotence, in the most humiliating manner, transferring executive powers to Congress," said Medvedev.
