A China-based firm that markets Western diesel generator sets attended the Spring 2018 International Trade Fair in Pyongyang, which also hosted companies supporting North Korea’s WMD and missile programs.

Taizhou Kaihua Diesel Generator Sets Co., Ltd's booth at the trade fair displayed a photo of a diesel genset. This photo closely resembles an MTU company genset that Taizhou Kaihua advertises on its website.
