None of the articles has anything to do with the stealth shaping on PAKFA to which you replied to. But back to the Y-20...
You are incorrectly assuming China, Russia and Ukraine come together to work on the Y-20 like European nations do with Airbus. Russian engines are merely temporary solution here to speed up the development process, not a permanent solution. Antonov provided initial inputs that may or may not used by China on the Y-20. The three countries are not working toward a common set of objectives. What's more, all three countries are trying to benefit themselves, not trying to benefit one another.
You are misrepresenting companies as countries. An aircraft requiring contributions from multiple companies does not mean it requires contributions from multiple nations. As an example, the F-22 is designed by Lockheed but uses an engine made by Pratt and Whittle. Both companies are American. Multinational cooperation is not a prerequisite for aircraft development.
You are also misrepresenting commercial aircraft as military aircraft. Airbus and Boeing produce aircraft for international customers who have their own requirements as well as political considerations. Naturally, that requires providing choices, including engines from a customer's own country. The same cannot be said for military aircraft such as the Y-20, J-20 and J-10 that are really meant for one customer.
The very fact that China spends money in developing domestic engines shows China is not trying to save money. Likewise, instead of investing money into IL-478 to save development costs, China spent its own money on designing a completely new transport that is the Y-20. Not only is China not trying to cut its R&D costs, China shows a trend of raising them. Your argument about costs and profits does not apply to China.
China's objective is to be completely independent in aerospace sector, not trying to be beneficial to Russian and Ukraine. Ukraine wants to use its Soviet technologies to exchange as much money as possible before those technologies become outdated. Out of the three countries, the only country that wants to cut R&D costs is Russia because the country still has financial trouble.
You are 110% right.
Just look at Russia's transport program. IL-476 is merely an IL-76 with a new engine (PS-90A).
Su-35, Su-33, Su-30, Su-34, Su-37 are all Su-27 with different roles.
S-400 is just S-300 upgrade with longer range.
AL-31FM, AL-31FN, 117S, and AL-31FM2 are all AL-31F with upgrade.

All the above evidences support that it is Russia who merely change names of its weapon systems in order to lure customer to think that they are new stuffs. In reality they are NOT. It is Russia that try to cut cost and reduce RnD.
China is the exact oppsite. It now has military budget twice that of Russia and still increasing it at 12% each year. !
