Shares opened lower Tuesday in Asia after U.S. stocks fell sharply just ahead of a new round of higher tariffs imposed by U.S. President Donald Trump.
Tariffs of 25% on Canada and Mexico were due to take effect early Tuesday. An extra 10% tariff is being imposed on China. On Monday, Beijing hinted via state media reports that it was planning retaliation that might at least partly focus on U.S. farm products and food exports. China is a major importer of U.S. soybeans and other agricultural products.
