Well, the ordinations and possible opening of Churches would not really affect the Han. The article says the majority of Orthodox in China are of russian descent (meaning they are the russians that have intermarried and their offspring). It will work for ex-pats and those Orthodox who work in China, it may include an ethnic chinese if the person legally married the 'outsider'.
Having a relationship with the chinese authorities is a good thing. In such cultures credibility comes from the top down. A softening even a possible conversion from some important figure can go a long way.
Good news though is from my talk with ethnic chinese Orthodox ( which I admit is not many -can be counted on one hand even if I have a missing finger) there is atleast one Orthodox monk from America who courageously has sneaked into China and has baptised a few ethnic Han.
