China promises to retaliate against latest US tariffs

China says it will retaliate against the latest and largest round of US tariffs.

Washington escalated the trade war on Monday, hitting China with tariffs on an additional $200bn worth of goods.

The US government will begin collecting a 10 percent tariff on those goods starting on 24 September, through to the end of the year.

Then on 1 January, 2019, the tariffs will jump to 25 percent.
