Instead of asking why, the question should rather be "why not".
China is not that far ahead in aerospace technology and no doubt is still playing catch up in some areas. So why arrogantly reject an opportunity to learn if the price is no far off, especially that it's from the same suhoi family.
Take a look at high speed rail: Chinese imported technology from Japan, Canada & Germany. Part of reason is to let them compete, part of the reason is to learn from everyone and come up with the best as its own.
Same goes with nuclear reactors. China imported technology from US, Russia, France. Does she have to? Probably not. But she is aiming to be the best, and the mentality is to learn as much as you can and innovate whenever possible.
If this purchase can help China learn about how to counter TVC equipped F-22, or speed up or improve its own program, it would worth it. China is to operate large number of Flankers for decades to come, and this deal is just a small investment to me.
