An article on cnbc.com included the following two observations: First, “A weaker yuan has been a key source of contention between the U.S. and China, with U.S. President Donald Trump accusing Beijing of intentionally letting its currency slide lower.” Second, the article quoted an investment analyst as arguing that some Chinese firms would be hurt by a weaker yuan because, “A lot of Chinese firms still have large U.S dollar-denominated debt.”

a. If the yuan gets weaker, will it take more yuan to buy a U.S. dollar or fewer yuan? 

b. Why would President Trump be concerned if the yuan was getting weaker? 

c. What is “dollar-denominated debt”? Why would Chinese firms with dollar-denominated debt get hurt by a weaker yuan?
