It's rumoured that China is currently developing a four-engine turboprop military transport plane called
Y-30, of which its size and payload is somewhere in the middle between the C-130J Super Herules and A-400M Atlas. Seems like this plane design is from AVIC.

Any news and updates on the Y-30 project?
Besides, I have also found a news article (dated 2016) which claimed that China is also developing large transport planes that are similar in size and capacity to C-5 Galaxy and An-125 Ruslan, which is aptly named
Y-40/50. The claim even went further for a "600 ton" supersized transport plane (i.e. basically An-225 Mriya's range).

Any news and updates on said large transport plane projects by China?
(CGI of Y-40/50 below for immagination of China's version of C-5 or An-124):
