Precisely, of the need to move quickly, China need to concentrate resources onto essential and pressing needs like W-15, WS-20, WS-10x engines for new fighter jets and lucrative commercial jet engines, and not on items that already have a steady and reliable supply, especially where modifications are needed to fit the new engines.If you don't establish demand for your product the industry will not take off and further R&D will become stunted.
The real battle has started now. Companies like GM are moving towards Carbon Matrix Composites for engine blades. For increasing stealth and performance, there is always the need to decrease IR signature while improving thrust.
You don't want to make a mistake like Indians who kept researching Tejas for 30 years. You need to operationalize thus technology so you get real world feedback and perform further research.
Failure of the Indians on the Tejas are more of their industrial incapability rather than strategy.
Of course industrial incapability could also result from past strategy failure.
