Over 1,400 university students from 37 countries and regions came to China for the 2008’s WorldMUN meeting(世界大学生模拟联合国大会). The meeting was held in Peking University from January 5th to 11st, 2008.

The idea of the WorldMUN began in 1991. A group of students at Harvard(哈佛)University wanted to make a new meeting to bring together the students who were interested in the world. They wanted to discuss different problems around the world. The WorldMUN is based on understanding, compromise, learning and friendship. The first meeting was held in Poland in 1992. After that, it is held in spring every year. Last year, it was held in Scotland.

This was the first time the WorldMUN meeting was held in Asia. It was also the biggest one in history. The students came from the best universities around the world.
