Chinese Communist Party members, in a subterranean way, will always be the power network inside of this bank.
Having done business in China since the year 2001, I can tell you that if there are no Communist Party collaborations in this bank or no informal groupings, it would be the only such organization in all of the PRC that this could be said of, and I don't believe that it's so. There may not be an officially registered party committee or cadre in the bank, but I believe that the operation and the collaboration is very similar to such in a more informal way.
