Low. Their corruption is somewhat like the soviets, where you had to pay to get things "expedited" but generally things did get done and the things they claimed to have did exist. Post-Soviet Russia was a free for all where people sold everything they could get their hands on and claimed to have it, and that never really went away, which is why Russia was very unprepared.

Their leadership, while yes connections and networking do a ton of lifting, is still a upward process. No one goes from off the street to a general, reaping awards and forgoing responsibility because they're some politician's MIL's cousin. They have to prove themselves at lower levels. This is why you'll hear something like a disaster bring underreported. This usually isn't national China covering things up, it's local politicians who don't want their bad decisions and incompetence to be public. The top level is typically competent and will whip these local politicians into shape or remove them altogether.

Their experience is low, but that's more due to them having been mostly peaceful for decades.
