Seoul (officially the Seoul Special Metropolitan City) is the capital and largest metropolis of the Republic of Korea (commonly known as South Korea). Seoul is the location of the 2014 United Nations Conference, and the location of a major Kaiju attack in 2020.
Following the four attacks in San Francisco, Manila, Cabo San Lucas, and Sydney, a United Nations conference was held in Seoul. The conference presumably lasted an approximate two days. On the second day, military consultant Stacker Pentecost demanded to know what the United Nations planned on doing against the Kaiju attacks.
Jasper Schoenfeld, a university professor, chose to present his idea for a weapon strong enough to fight the Kaiju. The seemingly absurd idea presented later prompted the twenty-one countries among the United Nations to "set aside old rivalries" and work together to create a non-military organization and specialized program that would help them create the defenses required to protect the Pacific Rim against their new enemy.
