This video says it is Shaghai SWAT. However the commentator is speaking Mandarin. Not unusual but Shanghainese is the main spoken dialect of the region. Linguistics aside, this officer is running on a wrapped ankle and is getting all his shots. 120 secs par time seems a bit long for only 10 steel targets. Steel Challenge or USPSA shooters could probably do this much faster. He is using a Type 79.
In this video, the officers are using what looks like a Type JS 9mm bullpup PDW
