Is the global trade war about to break out? Trump's new tariffs have triggered strong rebounds in many countries, and the global economy may face a new round of impact.

US President Trump formally signed an executive order on Saturday to impose tariffs on imported goods from Canada, Mexico, and China. Under the new policy, Canadian and Mexican goods will be subject to a 25% tariff, while Chinese imports will face a 10% tariff. Energy resources will receive a lower 10% tariff to reduce the impact on domestic fuel and home heating oil prices in the United States.

Trump posted on social platform X to explain the tariff policy, claiming that these measures are to address the threat of 'illegal immigrants and deadly drugs (such as fentanyl)' to American citizens. In addition, he warned that if affected countries retaliate, the United States may further expand the scope of tariffs or raise tax rates.

The annual trade volume between the United States and Canada, Mexico, and China is about $1.6 trillion, and these new tariffs will undoubtedly have a profound impact on the global economy. In Europe, the EU is closely monitoring this policy and is concerned about becoming the next target of a trade war.

The responses from various countries came quickly and forcefully. Here are the reactions of Canada, Mexico, China, and the EU to the new US tariff policy.

Canada quickly retaliated with $155 billion in punitive tariffs.

Canadian Prime Minister Justin Trudeau quickly responded by announcing a 25% retaliatory tariff on $155 billion worth of US goods. Among them, $30 billion worth of US goods will be immediately affected, with an additional $125 billion of goods.
