It all depends on Ukraine cooperation. They are currently building for China a wind tunnel to test large aircraft. They had signed an MoU two years ago for a JV, but the final contract is still unsigned. The MoU gave China three options, license production of An-70, design of IL-76 derivative, or joint development on a totally new design to be powered by Ukrainian engines. The way things are going, China is busy copying everything Ukraine ships her way. She is reluctant to hand over her bread and butter which is transport aviation which explains why the PTS is not signed. China currently doesn't even have the facilities to begin testing a design and without the help of Ukraine, it will be decades before they get one.
