Funny thing is, the company's detail from this website is still haven't been updated at all. However, with such escalation between Russia and Ukraine, the only thing China could make a deal is to using the old, globally obvious method same as purchasing the unfinished Varyag, and its blueprints that way.
No wonder the US is extremely pissed to see China have such of flexibility to 'steal technologies' by using front companies to buy foreign corporations, and then gone into dark instantly. However, the true crime of technology 'espionage' is greed, with money there's always have a work around.
Since China can make Y-20 by themselves, it's only matter of time to acquire more complicated aircraft blueprints, and I think if that's true, acquire An-225 before An-124 is a smarter move because of the famousness, and the downward development for smaller tonnage planes is easier than redesign a bigger version of An-124.
