Babu, China

With a population of just 65,603, Babu is a tiny outpost clinging to the border with Afghanistan. The town's remote location and proximity to conflict zones mean bureaucracy is a persistent headache for those looking to set up shop. Situated in the Balochistan province of Pakistan, Babu offers little beyond basic amenities - this is no vibrant, cosmopolitan hub. Those seeking a quiet, low-cost life on the fringes may find Babu appealing, but it's a tough sell for anyone else.
