I work with a lot of international offices in my line of work, and the two very worst are the mainland Chinese, and the Indians. For similar and different reasons. Either way, they are active obstructionists to productive solutions, and it infuriates me to the point of wishing harm on entire cultures.

Indians are friendly, but they are very lazy. They will not exert an ounce of effort to think outside the box for a solution. If an outside-the-box solution is spoon-fed to them, they will do anything they can to dump the problem onto the next shift rather than addressing it themselves.

Mainland Chinese are overtly hostile to anything that upsets the status quo. This is an utterly terrible attitude to have in a problem-solving line of work. They will actively sabotage any effort to actually solve a problem for the sake of "saving face" for even the biggest fuck-up involved (but only if the fuck-up in question belongs directly to their team; elsewise, they will actively seek to throw members of any other team under the nearest bus, even if that requires ten times the effort of simply working the issue).

Mainland Chinese will also willfully ignore any solution that does not fall squarely and entirely within pre-established rules and procedures. If something "colors outside the lines" by even a millimeter, they will reject it entirely no matter how slight the inconvenience, and with complete disregard to impact upon internal colleagues, or even high-profile customers.

Another unforgivable offense that the mainland Chinese adhere to religiously is the whole "saving face" bit. If even the lowest monkey suggests a bad course of action to a customer, the entire chain of command will adamantly refuse to change course of action, no matter how severe the impact to the customer, no matter how slight the change required. Refusal to admit wrongdoing trumps doing right by the customer, trumps saving massive resources on our end, trumps anything. Once someone Chines does something wrong in customer view, it will sooner go to engineering to design an entire new way of implementing the product, rather than simply sending a short email to a customer to correct an internal error.
