WASHINGTON- China and Russia hit back at America with $34billion of import tariffs in retaliation to the tariffs imposed by USA.
US tariffs on $34bn (£25.7bn) of Chinese goods came into effect on Friday.
Accusing USA of starting the largest trade war in economic history, China's commerce ministry lodged a new complaint with the World Trade Organization (WTO).
Russia is also introducing extra duties on a range of products imported from the US.
The situation further aggravated after Donald Trump announced that they might target Chinese goods worth $500bn in additional tariffs.
The American tariffs are the result of Mr Trump's attempt to protect US jobs and stop what he calls "unfair transfers of American technology and intellectual property to China".
