According to the latest news, White House officials announced on February 11th local time that the United States plans to impose a 25% tariff on steel and aluminum imported from Canada. If implemented, this measure will overlap with other tariffs in Canada, resulting in a tariff barrier of up to 50% for Canadian steel and aluminum exports to the United States. This news quickly sparked widespread attention in the global steel and aluminum industries.

On February 10th, US President Trump signed an executive order announcing a 25% tariff on all steel and aluminum imports into the United States. When signing the order, Trump stated that this move aims to protect the domestic steel and aluminum industries in the United States and create more job opportunities. However, this decision has also sparked widespread controversy and opposition from the international community.

Canada, as an important trading partner and ally of the United States, expresses strong dissatisfaction with this decision made by the United States. Upon learning of the news, Canadian Prime Minister Trudeau immediately stated that imposing tariffs on Canadian steel and aluminum is completely unreasonable. He emphasized that the economies of Canada and the United States are integrated, and imposing tariffs will have a negative impact on both sides' economies. Trudeau also stated that if the United States really implements this tariff measure, Canada will take a firm and clear response to protect the interests of Canadian industry and workers.

In addition to Canada, the European Union and several other countries have also expressed opposition and concerns about the United States' decision. The Executive Vice President of the European Commission, Shevchenko, stated that the EU will take resolute and appropriate measures to safeguard its economic interests. German Chancellor Scholz also stated that the EU will take joint action to respond to this move by the United States. In addition, countries such as South Korea, France, Spain, and Brazil have also stated that they will respond accordingly based on the measures taken by the United States.

This decision by the United States has not only sparked controversy and opposition in the international community, but also had a profound impact on the global steel and aluminum industries. Steel and aluminum are important raw materials in many industrial sectors, and their price fluctuations directly affect the production costs and profits of related industries. Therefore, the US tariff measures will have a significant impact on the supply chain and market structure of the global steel and aluminum industries.

In addition, this decision by the United States may also have a negative impact on downstream industries in the country. Steel and aluminum are widely used in various fields such as automobiles, construction, and machinery, and their price increases will directly lead to an increase in the cost of related products, thereby affecting consumers' purchasing willingness and overall market demand. Therefore, the US tariff measures may trigger a series of chain reactions, causing adverse effects on the US manufacturing industry and job market.

In summary, the decision of the United States to impose a 50% tariff on Canadian steel and aluminum exports to the United States has caused a shock and controversy in the global steel and aluminum industry. This decision will not only have a negative impact on Canada's economy and industry, but may also have adverse effects on downstream industries and job markets in the United States.
