While being light on details, Strategy Page reports that the Chinese PLA has decided not to expand its arsenal of shotguns, considering them a riot control weapon rather than a combat weapon.
The Chinese police and army shotgun is the Norinco / Hawk Industries manufactured Type 97-1. It is a copy of the Remington 870. Ironically, the shotgun is imported by Remington (via. Marlin via. H&R) as the H&R Pardner shotgun.
UPDATE: Strategy Page was not entirely correct. China is instead adopting the QBS 09 shotgun.
