China is a People's Republic governed by the Communist Party of China. However, in its economic system, it is no longer a communist, but a "socialist market economy", a kind of combination of a planned economy and a market economy.  Today, China is considered a political, economic and military superpower.

-North Korea is a state in East Asia, on the North Korean Peninsula. Neighboring countries are South Korea in the south, Russia and China in the north. The state is a socialist one-party system and is run by the Korean Labor Party, which is usually considered as communist in the West. However, all references to communism were removed from the country's constitution in 2009. North Korean ideology is based on the Juche idea; outside the country it has been described as a Stalinist dictatorship.

-South Korea occupies the southern part of the Korean peninsula. The only land border is the 243 km long border with its northern neighbor, North Korea.

With around 51.7 million inhabitants, South Korea is one of the 30 most populous countries in the world and with over 500 inhabitants per square kilometer one of the most densely populated countries. About half of the inhabitants live in the metropolitan area of the capital Seoul, a world city with the fourth largest economy worldwide. Over two million people each live in the cities of Busan, Incheon and Daegu.
