Metro, Seoul, South Korea

After the invasion of South Korea by forces from the North on 25 June 1950, the resulting war between the two Koreas ended with an Armistice Agreement, but the border between the two nations is the most heavily fortified in the world. After the war, the South Korean economy grew significantly and the country had transformed into a major economy, a full democracy, and a regional power in East Asia.
South Korea is a presidential republic consisting of sixteen administrative divisions and is a developed country with a very high standard of living. It is Asia's fourth largest economy and the world's 15th (nominal) or 12th (purchasing power parity) largest economy. The economy is export-driven, with production focusing on electronics, automobiles, ships, machinery, petrochemicals and robotics. South Korea is a member of the United Nations, WTO, OECD and G-20 major economies. It is also a founding member of APEC and the East Asia Summit.
