The list includes a number of cities in China, where massive growth is underway and new metropolises are rapidly emerging.
"[O]ur list focuses on emerging powerhouses like Chongqing, China, (population: 9 million), which Christina Larson in Foreign Policy recently described as "the biggest city you never heard of."
Chongqing sits in the world's most important new region for important cities: interior China. These interior Chinese cities, notes architect Adam Mayer, offer a healthy alternative to coastal megacities such as Shanghai, Hong Kong, Shenzen and Guangzhou, which suffer from congestion, high prices and increasingly wide class disparities. China's bold urban diversification strategy hinges both on forging new transportation links and nurturing businesses in these interior cities."
