Figure 9.15 is a 2014 image of the Korean Peninsula taken from the International Space Station. It shows North Korea in the dark except for the capital city, Pyongyang. The largest bright area is Seoul, South Korea, located just across the border. China, Vietnam, and Laos are also communist countries, but their economies are more open even if the freedoms of their citizens are curtailed.
