dear sir,or madam,

             once upon a time, new york times's website was also banned in china,until the editor of new york times get a chance to complain directly to the president of china--jiang zemin.from then on, the website of new york times is never banned.i think you need to find a way to talk to the current president of china--hu jintao,and get a promise from him that wiki won't be banned again.

             lots of celebrities are also fan of wiki,you can have them give lectures about this accident in some  very formal occasions,for example,li kaifu,the hotcake between microsoft and google,if he talk about this in tsinghua university's lectures,the government will be embarrassed and make some recessions.
