Stocks decline on Asian, European markets after Trump imposes tariffs, ahead of Wall Street opening

The stock markets in Europe and Asia fell oversight after President Donald Trump this past weekend announced tariffs on Canada, Mexico and China, and said tariffs on the EU would "definitely happen."

The German and French stock markets were down about 2%, and London's FTSE 100 dropped more 1%, according to the British Broadcasting Corporation.

However, the U.S. dollar strengthened on the currency markets as the Canadian dollar plunged to its lowest level since 2003, the BBC also reports.
