Not quickly. they cant build their jet engines and rely on other places for them.

They've used Russian engines in the past, but they have started using they own recently. I haven read anything about what's in the H-20, but they are very good at stealing tech and manufacturing, so I wouldn't assume they will continue to be reliant on importing engines.

Back in 2013 China announced that it was investing $16 billion in an effort to fix some of its problems encountered manufacturing high-performance (as in world-class) jet engines. Although China has been working on this for over three decades, continued problems with materials durability, efficient design and quality control have prevented Chinese engines from being competitive with Western models. That large investment appears to have paid off because by 2019 all new Chinese jet fighters were entering service with one of several variants of the WS10 engine.
