Danish shoppers are boycotting American products to protest President Donald Trump’s stance on Greenland and trade tariffs, according to CNBC. Danish consumers are protesting by refusing to buy American products in response. The supermarket chain Salling Group added asterisks to European-owned product labels in stores to help shoppers identify them, responding to customer demand rather than promoting a U.S. boycott. The #BoycottUSA movement has spread across Europe and Canada.
