[Canada calls to halt purchase of U.S. Black Hawk helicopters before Canada-U.S. trade negotiations] October 15th, according to Canadian news on the 14th, the Canadian government had quietly ordered a suspension of the purchase of 16 U.S.-made UH-60M Black Hawk helicopters before starting a new round of trade negotiations with the United States. According to sources, multiple sources revealed that the decision to suspend purchases is related to trade and diplomatic tensions between Canada and the United States. As Canada seeks to reduce its military dependence on the United States, the government believes the timing is not right to purchase U.S. helicopters without a competitive bidding process. In addition to suspending the purchase of Black Hawk helicopters, the Canadian government is also continuing to review whether it will purchase a batch of F-35 stealth fighter jets produced by American companies.
