美国宣布禁止进口加拿大乳制品、酒精和机动车

美国宣布将从2026年9月29日起禁止进口加拿大乳制品、酒精饮料和机动车产品12。此举是特朗普政府对加拿大实施的新一轮贸易措施的一部分，同时还将对床垫、游艇和高尔夫球车等商品征收50%的关税，该关税措施将从2026年9月15日起生效2。

这些举措是在加拿大对约200亿美元美国商品征收最高50%报复性关税后宣布的2。特朗普政府官员称该禁令旨在"确保保持公平的竞争环境，阻止报复行为，当然也是为了保护美国生产"2。加拿大总理卡尼对此作出回应，表示"这是为了确保没有国家能将我们作为人质，我们能够按照自己想要的方式生活"2。卡尼还宣布计划下周前往斯特拉斯堡向欧洲议会发表讲话2。

The United States has announced sweeping trade measures against Canada, including import bans on dairy products, alcohol, and motor vehicles set to take effect on September 29, 2026.12 Additionally, the Trump administration will impose 50% tariffs on mattresses, yachts, and golf carts beginning September 15, 2026.2 These actions represent a significant escalation in trade tensions between the two countries, following Canada's retaliatory tariffs of up to 50% on approximately $20 billion worth of American goods.2

A Trump administration official justified the measures by stating, "President Trump is doing this to make sure, again, that we keep a level playing field, deter retaliation, and of course protect American production."2 The escalating trade conflict comes as approximately 68% of Canadian exports go to the United States, with roughly 80% of imports under the USMCA agreement entering duty-free.2 In response, Canadian Prime Minister Chrystia Freeland declared, "It's about ensuring that no country can hold us hostage. And that we can live how we want to live."2 Freeland has announced plans to accelerate reducing Canada's dependence on the United States and will travel to Strasbourg next week to address the European Parliament.2
