Given that it's got Isuzu mudflaps and that this photo was taken in Chongqing, I would have thought that this is Qingling-Isuzu QL-Series pickup with some weird aftermarket canopy (Chongqing is where they make chinese-built Isuzu's), BUT, after doing some sleuthing, it appears that it's called Dima DMT5031XKC (Investigation team car) (Manufacturer: Chongqing Dima Industry Co., Ltd.), which is based on QL-Series chassis, made by Qingling Motors Co., Ltd., China.
