The abandon of WS-6 project did do not mean that China gives up independent aircraft engine manufacture. In 1980, China started to implement a plan, High Performance Propulsion System Preliminary Development (HPPSPD), to focus on basic research on engine components. March 29th 1982, US famous "Aviation & Space Technology Week" had a report with title of "China Waiting for CFM-56II Turbofan Exportation". The report said that China purchase 2 CFM-56II Turbofan engines to exchange China's Trident airliners' old ones. U.S. DOD (Department of Defense) worried about this exportation, because CFM-56 is based on the core of the F101-GE-102 engine which was used in B-1B Lancer Bomber. Despite of the dissidence, U.S. government still authorized this exportation in 1980s' Sino-U.S. HoneyMoon Relation. Actually, some resources from China showed that the development of WS-10 just bases on the core engine from CFM-56. And WS-10's final object, is F110 engine. WS-10 project got directly supports from top leader of China. In January 1986, Deng Xiaoping passed a new plan on China's Turbofan engine development. One year later, 606 with its attached department formally initial the development of WS-10, code name Taihang, for China's third generation fighter J-10.
