China


China is the world's most populous country. It has a continuous culture stretching back nearly 4,000 years and originated many of the foundations of the modern world. After stagnating for decades under the rigid authoritarian socialism of founder Mao Zedong, China reformed its economy along partly capitalist lines to make it one of the world's fastest-growing, as well its leading exporter. China is now a major overseas investor, and is pursuing an increasingly assertive foreign and defense policy.

North Korea 


For decades North Korea has been one of the world's most secretive societies. It is one of the few countries still under nominally communist rule. North Korea's nuclear ambitions have exacerbated its rigidly maintained isolation from the rest of the world.

South Korea


South Korea has developed into one of Asia's most affluent countries since partition in 1948. The Korean War ended in 1953 without a peace agreement, leaving South Korea technically at war for more than fifty years. The following four decades were marked by authoritarian rule, during which government-sponsored schemes encouraged the growth of family-owned industrial conglomerates, including the Hyundai and Samsung groups.
