But, there are things about those engines that the PLAAF and PLAN have not accomplished yet, and would like to dearly learn how to do.I believe there are quite a number of things China could learn from the Su-35, such as how the Russian handles advanced radar and information integration, and how they achieve super maneuverability with advanced flight control. China may have similar system themselves but it will always help to see how others tackled the problem (to a certain degree, not that they will get all the source code and know-how). It may also give them more ideas on how to squeeze the most out of future J-11/15/16 variants. Last but not least, they will have a high-performance target to benchmark their own products with.
As for the engines, I'm sure they'd be interested to take a look and get some valuable knowledge about how the Russian develops a newer generation engine. But this may not be any more important then other aspects of things. I'm saying that because the development cycle for engine is very long, and it'd be way too late if they really wanted to use this to aid WS-15 development (if that is the case then this deal would not have dragged so long). Every different turbonfan is a tightly integrated system that its parts could not be easily interchanged, given that newer Chinese engines are not based on the same core and configuration of the 117s, there won't be much they could take from it and apply on current projects.
This would be a great opportunity to do so...among other things that you also listed.
