U.S. President Donald Trump has just slapped new tariffs on 14 countries, with some as high as 40 percent! Myanmar and Laos have taken the biggest hitsfacing 40% tariffs. Others like Japan, South Korea, and Indonesia are also on the list. They are all part of what Trump calls a plan to fix 'unfair trade deals' and protect U.S. jobs. Trump sent letters to major trading partners, including Japan and South Korea, dictating new blanket tariffs - The letters, which caused US stocks to tumble, are a message to those countries where White House officials "don't believe that trade talks are going particularly well," a former trade negotiator said. The notices also deal a blow to "hopes that Trump would scale back tariff threats and de-escalate a trade war," some experts argue.
