US President Donald Trump on Wednesday announced that a 25% tariff would be imposed on automobiles imported into the United States. The US government argues that it is an effort to bring back manufacturing jobs to the country. The tariffs have drawn criticism from all across the World, with the Canadian PM Mark Carney saying "This is a very direct attack. We will defend our workers. We will defend our companies. We will defend our country." NDTV World's Vishal Vivek sheds light on the story.
