Hunchun, China

With over 239,000 residents, Hunchun is a sizable border city, but one that comes with its fair share of headaches. The Chinese government has poured billions into transforming this strategic hub, yet bureaucracy remains a persistent challenge. The city's climate is also a mixed bag, with long, cold winters that can test the resolve of even the hardiest expat.

That said, Hunchun's location at the intersection of China, Russia, and North Korea makes it an intriguing outpost for those seeking access to these markets. Its export processing zones and trade ties with Rason, North Korea could appeal to adventurous business types. But for the average American, the hassles may outweigh the rewards.
