This company was chosen to manufacture the locally designed 4wd jeeps which replaced outdated American off-roaders and the Russian GAZ. The Beijing BJ210 and its bigger brother, the BJ212 became the standard military vehicles for decades to come.
Welcome to the Chinese Car Forum. It's nice to see you have an interest in Chinese made vehicles.
With regard to the jeeps, I think you have this company confused with another. Have a look under the section "Beijing Auto Industry Holding".
The Soueast company has been manufacturing mainly Mitsubishi-based sedans and minivans and lately Sprinter vans as well. But no jeeps to my knowledge.
If you are interested in jeeps and off-roaders you will find a bunch of threads in here dealing with them.
