You can read about China's modern carrier-based, stealth fighter here: https://en.wikipedia.org/wiki/Shenyang_J-35

There is a section about its engines: https://en.wikipedia.org/wiki/Shenyang_J-35#Engines

The first engine they used for the J-35 was the RD-33 (designed/built in Russia): https://en.wikipedia.org/wiki/Klimov_RD-33#RD-93 - It was not efficient enough for the J-35 and generated black smoke trails. China decided to design & build a China-based engine.

This is the engine for the early J-35 prototype, WS-13 built in China: https://en.wikipedia.org/wiki/Guizhou_WS-13

This is the production engine for J-35, the WS-19: https://en.wikipedia.org/wiki/Guizhou_WS-19

China has built 50+ J-35 aircraft, and is scaling up production to support their domestic military, and also export orders to other militaries (including Pakistan, and possibly Russia).

Interesting: This is China's latest aircraft carrier, which has electromagnetic catapults, instead of steam-based: https://en.wikipedia.org/wiki/Chinese_aircraft_carrier_Fujia...
