Regarding "Proof of no criminal record abroad recognized by Chinese embassies."

What does this mean? Does the criminal background has to be done with The FBI or does it have to be both DOJ and FBI? Are there any details? We were thinking Live Scan but the process is much more complicated than we expect as we do not know what ORI number to fill in because technically we are the ones who are requesting the background but the ORI is only given to agencies and not to individuals.
