I'm sorry I can't be of too much help here... but I did find these two links on google (amongst thousands!) http://www.china.org.cn/english/2002/Oct/46138.htm
http://www.findarticles.com/p/articl...5/ai_112132022
The latter link dealing with "why" and the first explaining the law of the "one child policy"... hope this can be of some help!
