Ramp checks I've had from the CAAC are little different to any other agencies. The guys are courteous, polite and thorough and seem to use the ICAO standard (if there is one). The only thing different which my operator has done recently as the result of a ramp check feedback is include a paper copy of the AOC since we removed the paper manuals which had a facsimile of it. They will scrutinise your licences very carefully.
