#10 Taiwan
Clocking in at number 10 on our list of largest foreign holders of US debt is Taiwan, with $183.1 billion worth of Treasury securities at the end of November 2016. Taiwan is one of the four Asian Tigers (along with Hong Kong, Singapore, and South Korea) and has a tech-based export economy. Due to its export economy, the country incidentally has an excess amount of dollars, which it uses to buy U.S. Treasury bonds.
