The Harbin Z-6 was an attempt by China to develop an indigenous helicopter, but the project was eventually cancelled due to a number of problems. It is often referred to as a Chinese version of the Mi-8, but in fact has absolutely no relation to the Mil design whatsoever, and was actually a development of the earlier Mi-4/Z-5. It retained essentially the same basic fuselage structure, but with a new, and repositioned, turboshaft engine, together with a redesigned forward fuselage.
