As a leading manufacturer of special-purpose vehicles in China, Chengli offers the most comprehensive product range and qualifications in the industry. Wave after wave of large orders have underscored the strength of Chengli's special vehicles. The following is a batch of special vehicles procured by the United Nations: In early September 2017, four new Dongfeng all-wheel-drive 6x6 special vehicles produced by Chengli Group were completed and, having passed customer inspection, shipped to Shanghai Port for onward delivery to the United Nations. These vehicles are built on Dongfeng all-wheel-drive chassis, combined with Chengli's advanced manufacturing processes.

The vehicles include a sewage suction truck, a fuel tanker, and a water transport truck, with the United Nations as the end customer. This first batch of four units is being followed by additional orders already in production.

It is understood that various special vehicles produced by Chengli Group have over the years been regularly procured by UN agencies and by China's Ministry of Commerce for foreign aid projects.
The Chengliwei series of new special vehicles is built by Chengli's high-end plant, which holds qualifications for manufacturing new-type special vehicles. Chengliwei high-end new-type vehicles have been widely praised by military commands. The new special vehicles procured by the United Nations are all-wheel-drive models (such as 4x4 and 6x6 chassis vehicles) suited to extreme terrain including deserts, muddy ground, and roadless wilderness, and are particularly favored by customers.
