Oh wow, I'm shocked.
India spent 23 years (since 1989) on the Kaveri engine and now, they're walking away?
Sheesh, give me all the schematics, prototypes, and the test data results.
I'll cobble together a group of Chinese engineers armed with abacuses. We can fix anything!

"[T]he Kaveri had a tendency to 'throw' turbine blades, which required securing blades from SNECMA (as well as digital engine control systems).[6]"
"Among its deficiencies, CAG says the engine weight was higher than the design specifications (1235 kg against 1100 kg) and there was no progress on developing the compressor, turbine and engine control systems.[25]"
The Kaveri had been tested to a maximum of 0.7 Mach.
"'In recent times, the engine has been able to produce thrust of 82 Kilo Newton but what the IAF and other stake-holders desire is power between 90—95 KN', senior officials told The Hindu."

Chinese WS-10A turbofan engine produces 132 KiloNewtons of thrust
China's WS-10A engine (with gearbox at the bottom) is designed to power the J-10B Vigorous Dragon fighter. This version of the WS-10A turbofan engine is said to have 13.2 ton maximum thrust. There are several wrapped engines near the floor.
To put things in perspective, China's WS-10A engine produces 132 KiloNewtons of thrust. The in-limbo Indian Kaveri engine can only manage 82 KiloNewtons.
The Chinese WS-10G engine, which is currently undergoing reliability tests, can produce 155 KiloNewtons. It's the equivalent of two Kaveri engines.
Shenyang WS-10 - Wikipedia, the free encyclopedia
"Variants
WS-10 - original design producing a thrust of 126 kilonewtons (28,000 lbf)
WS-10A - upgraded variant producing a thrust of 132 kilonewtons (30,000 lbf)
WS-10B - upgraded thrust-vectored variant producing a thrust of 132 kilonewtons (30,000 lbf)
WS-10G - upgraded variant producing a thrust of 155 kilonewtons (35,000 lbf) with Thrust Vectoring and stealthy nozzles that have jagged edges and tiles"

A Chinese WS-15 turbofan engine for J-20 Mighty Dragon produces 180 KiloNewtons of thrust
China's WS-15 turbofan engine for J-20 Mighty Dragon produces 18 tons of thrust.
For comparison, each of the Pratt & Whitney F119-PW-100 engines that power the F-22 produces only 156 KiloNewtons of thrust. However, the F-22 is a smaller and lighter plane than the J-20.
WS15
"WS15 turbofan
The core engine for the WS-15 engine was first tested in April 2005. The demonstrator was developed successfully and the prototype WS-15 was running smoothly. China is undoubtedly far behind Russian engine technology. Nonetheless, China has produced the WS-9 engine for the JH-7, the WS-10A engine for J-10, and the WS-15 for the new J-20 fourth generation stealth fighter. The WS-9 and WS-10A were both usable, and without the WS-10A China would not have negotiated J-10 orders with PAF."

WS-15
Program Status: Under Development
IOC:
2020
Origin: China
Description:
The WS-15 is a Chinese advanced turbofan intended to power fifth generation fighter aircraft. The WS-15 thrust may exceed 18,000 kg and is intended to power the People's Liberation Army Air Force (PLAAF) J-20 twin-engine stealth aircraft and the J-12 single engine stealth fighter.
Applications:
Strike & Fighter Aircraft"
