During Donald Trump's administration, there were significant changes in U.S. trade policy, one of which was the increase in tariffs. He imposed high tariffs on various countries, including China, primarily aimed at protecting U.S. industries and jobs, and reducing the trade deficit. The Trump administration imposed hundreds of billions of dollars in tariffs on Chinese goods in 2018, which later became known as the 'trade war.' This tariff policy created tensions in international trade and had negative impacts on American consumers and businesses in some cases. According to Trump, it was necessary to protect U.S. interests, although there is divided opinion among economists on this matter.
