The tiny southern African kingdom of Lesotho has been hit with a 50% reciprocal trade tariff by U.S. President Donald Trump, the highest levy of any single state on his long list of target economies. Lesotho, which Trump had ridiculed in March as a country "nobody has ever heard of", is a poor and landlocked country with a gross domestic product of just over $2 billion. It has a large trade surplus with the United States, mostly made up of diamonds and textiles, including Levi's jeans.
