Let's remember that is China we are talking of, where shady deals, politically influential individuals and lots a money can often sway otherwise logical decisions. Comrade Chairman Liu, MU current CEO, has been closely associated with French interests since its days at China Southern, and his political connections were evidently strong enough to allow MU switch from OW to ST. Such kind of deals however are always dependent on the political mood of the time and the speed in which individuals can adapt to changing situations , so I would not assume that MU membership in ST is written in stone, or in other words, that CA will remain in * for the foreseeable future.
