Between Trump`s 2017 and March 2019, the U.S. trade deficit widened by $119 billion to $621 billion, its highest level since 2008.  In January 2020, the Trump administration imposed tariffs on 16.8% of all products imported into the United States (measured by the value of all U.S. imports in 2017).  The Congressional Budget Office (CBO) released its estimate of the economic impact of Trump`s trade policy in the United States: China launched a WTO complaint on April 9, 2018 against U.S. tariffs on steel and aluminum.  The EU opened a similar procedure in the WTO on 1 June 2018.  By 2019, the Canadian steel industry employed more than 25,000 workers and contributed $3.8 billion to Canada`s gross domestic product (GDP). In the same year, the Canadian aluminum industry employed about 10,000 workers and contributed $3.1 billion to our GDP. On June 13, 2019, 661 U.S. companies sent a letter to Trump asking him to settle the trade dispute with China. The letter was one of many people sent on behalf of Tariffs the Heartland, an organization of more than 150 trade groups representing agriculture, manufacturing, retail and technology.
  Jean-Claude Juncker, President of the European Commission, condemned US tariffs on steel and aluminium and announced that a legal challenge would be followed by the World Trade Organization.  The EU filed a complaint against the United States on 1 June following the entry into force of the tariffs.  The governments of the United States, Canada and Mexico have worked together within the NASTC to develop coordinated positions on issues of multilateral areas important to steel, including the OECD Steel Committee and WTO rules negotiations. In November 2018, Trump argued that tariffs have enriched the United States. He said the U.S. earns “billions of dollars” on “tariffs charged to China.” He added: “If companies don`t want to pay tariffs, build differently in the United States, let`s make our country richer than ever!” Auditors and economists have called Trump`s claims false, with the Associated Press writing, “Almost all economists say the president is wrong. That is because tariffs are taxes on imports. They can lead to higher prices, reduce trade between countries and thus affect overall economic growth.   Trump has repeatedly promised to reduce America`s trade deficit and has spoken out in favor of renegotiating trade agreements and imposing tariffs to that end.   Despite these efforts, the trade deficit has continued to grow in 2018.  Customs negotiations in North America have been relatively more successful: on May 20, 2019, the United States lifted tariffs on steel and aluminum on Canada and Mexico and joined Australia and Argentina   On May 30, however, Trump unilaterally announced his intention to impose a 5% tariff on all imports from Mexico from June 10, tariffs would increase by 10% on 1 June July and 5% each month for three months, “until illegal migrants pass through Mexico and into our COUNTRY STOP,” adding illegal immigration as a condition for customs negotiations between the United States and Mexico.
