China

A 10% charge on all goods imported from China to the US took effect on 4 February.

In response, China said it will implement a 15% tariff on US coal and liquefied natural gas products from 10 February. Crude oil, agricultural machinery and large engine cars will see a 10% tariff.

“Trade and tariff wars have no winners,” said a spokesperson at China’s Washington embassy.

Canada

Canadian Prime Minister Justin Trudeau said Trump’s proposed tariffs of 25% on Canadian goods – which were also set to begin on Tuesday – “will be paused for at least 30 days while we work together”.

Trudeau’s retaliatory 25% tariffs on 155bn Canadian dollars’ worth ($107bn; £86bn) of US imports were also halted.

In exchange for the pause, Trudeau said Canada was implementing a “$1.3bn border plan” to add “new choppers, technology and personnel to border,” as well as “increased resources to stop the flow of fentanyl”.

Much of the border security plan had already been announced in December.

Trump said the delay would allow the US to see “whether or not a final economic deal with Canada” can be reached.

Mexico

The proposed 25% tariffs against Mexico have also been delayed a month, as have measures by Mexico against US goods.

Mexico’s President Claudia Sheinbaum agreed to send 10,000 members of the National Guard to the US-Mexican border to “prevent the trafficking of drugs, in particular fentanyl”.

President Sheinbaum said the US had in turn agreed to increase measures to prevent the trafficking of high-powered US weapons into Mexico.
