China already has an A320 final assembly plant located not too far from Beijing. So the A320 you may be flying in the future, may infact be assembled in China!
I am sorry to say these Assembled in China Airbus A320s may only distribute to Chinese carriers only due to different market price per order. ( I guess.)
And also there are larger amounts of orders from Chinese carriers so they may only in Chinese market. Like those assembled in China Audis, Merceds, BMWs,ONLY THERE WITHIN Chinese market.
