Stephanie Gauthier
The 25% tariffs imposed by Trump, along with the retaliations that could ensue, risk worsening economic tensions between the United States and its major trading partners, Canada and Mexico.
Implementation

Just a few hours after his presidential inauguration, Donald Trump officially announced the date for implementing his threat to impose tariffs of 25% on his two neighboring and allied countries, Canada and Mexico.
February 1st

These significant trade retaliation measures against Canada and Mexico will take effect on February 1st.
Canada reacted

Canada reacted firmly to President Donald Trump’s announcement of imposing a 25% tariff on Canadian imports.
Ottawa

Ottawa has said it is prepared to take equivalent retaliatory measures if necessary and has promised to respond proportionately to these tariffs.
A Call for Calm

Under the presidency of Claudia Sheinbaum, the Mexican government has called for calm in the face of recent decisions by Donald Trump.
The Threat

Notably the threat from Trump to impose tariffs of 25% on Mexican imports.
On sovereignty

She recalled that such measures had already been implemented during Trump’s previous term and reaffirmed Mexico’s commitment to defending its sovereignty.
Possible Retaliations

The 25% tariffs imposed by Donald Trump, along with possible retaliations, could exacerbate economic tensions between the United States and its trading partners.
Canada, Mexico and... Colombia

This situation particularly threatens relations with Canada and Mexico. However, Trump could not help but already impose a 25% tariff on Colombia after the country refused to allow planes carrying deported migrants from the United States to land on its soil.
A Rise in Costs

These measures are likely to disrupt supply chains and lead to an increase in costs for consumers.
The three economies

They could also provoke trade reprisals, negatively affecting the three closely linked economies.
