Globalization does not fix borders, just interests.
Y-20 has russian engines, i wonder if Russia would stop selling Al-31s or D-30 what would happen to Chinese air force?
I begin to wonder whether you're sober or not under influence of narcotics when you typed those things...
First, for that one...now, the odds of Russia to default a signed-and-paid deal would be low unless there're terms and conditions included that'd bind what the engines are allowed to be used for...the biggest unknown would be when it's due for new negotiations for new purchases, Russia could very well set the price and delivery quota that's not favorable to the Chinese.
In that way, China will have no choice but to rely on the stocks at hand and accelerate domestic programmes for replacements, which in the short terms will undeniably affect the tempo of PLAAF & PLAN aviation which using those engines.
You can see globlalization in Chinese aircraft programs, Cooperation with Russia and Ukraine in J-10, Z-10, JL-15, J-11, cooperation with Europe in airbus and Eurocopter aircraft build in China, with Canada with Bombardier, with US in B787, with Brazil in ERJ-145.
China is very well in depth in Globalization
what happens here people want to deny any foreign input.
China has chose the way of tech transfers by the west and Russia to China in exchange of sales by Sukhoi or Airbus in China.
ARJ-21 and C919 are also globalized products more in tune with the realities of the modern world.
You're mixing the commercial programmes and military ones, you might fool the average Joe on the street but not us "SDF regulars" here. Everybody knows CAIC and its subsidiaries are making components for Boeing, Airbus and Eurocopter, even with the embargo still in force to this day after 1989 such business never stopped, and Chinese aviation industries managed to garner the badly needed modernization experience through these "outsourcing business opportunities".
Things get complicated when comes to weapons programmes. Other than things like engines which are obvious to spot, the foreign factors in various post-1990s Chinese weapons programmes are very difficult to confirm via independent and creditable sources, as everybody likes to take credit for it.
J-10A obviously have a special variant of the Al-31 engine; Z-10 have unknown input that for the past 2 decades credited to European and South African, and now Russia; JL-15 has obvious Yak-130 influence but to what extent is unknown, not until more official disclosure and close examinations in other airshows; J-11 deals comes as part of the package when importing Su-27, certainly something that generous won't be possible today but that was back in the 1990s, when Russia either cut a neat deal or starve to death...by the time of J-11B Chinese have "improved" upon it like they did with the MiG-21 into J-7.
Competition has being taken by these foreigners in two ways.
If China builds Y-20 for example, Russia is selling D-30s and making new engines, so they consider these sales will help their firms to upgrade and stil remain ahead of China in the world markets, that is the way also Airbus and Eurocopter think.
And like I said before, Y-20 won't score much in the global market, nor it'd need be. Market for cargo jets that has rough field capability (that is, not like civilian jets that has strict demand for paved runways) is a niche one, those who has such demand would be rich enough to buy C-17, or Il-76/478 if on a pinch, as both have the advantage of logistics that China can't provide - China's market are those either too poor to afford even Russian goods, or blacklisted by the US. These banana states and rogue states don't have the budget or demand to justify a cargo jet the likes of Y-20. Y-20 is made to answer the demand of PLAAF and PLAN aviation.
Others if they think China demands too much tech trasnfers, simply they move to other emerging marktes for design or manufacture.
The prima-delta problem everyone faces is funding - even amongst the Chinese they've to fight for funding, since government is the biggest pie in town the government deal always first and commercial second. Russia's problem is mostly "when the government deliver?" kind, so their companies and manufacturers have to rely on foreign investors...certainly they know what the Chinese are up to, so someone as gullible as the Indians come along with crates of hard currencies, that's god-sent for them.
I'm inclined to believe that the Indians realized that they got conned, but with US did left them dangling in the wind still fresh in their memory, Europe's either too expensive or too unstable an effort,and their local effort still mediocre at best, Russia is the better bet right now for them.
