This may be a dumb question, but why are these plane turboprop not jet engine?

better fuel efficiency in subsonic, much longer airborne time

...plus, Chinese turbofan wasn't that reliable when Y-8 was out...

But j7 and etc are jets.

Turboprop planes require a shorter runway for take off and landing. Hence more suitable for using China's South China Sea island bases.

Fighter jets use low bypass turbofans while large planes like tankers, airliners, etc... use high bypass turbofans. The Chinese engine industry has been focused on low bypass turbofans so they have progressed much faster than high bypass turbofans, the first of which are still in testing phase for the Y-20 and C-919.

no I think it was from last RAN P8 documentary on CNN

Hi can’t these P8 operate from Guam in case they have to take place of American P8s
thank you

The answers above plus until Y20 and C919 lines get hot enough there’s just not a jet suitable available. Y20 could be converted to such but the bigger needs are transports and tankers besides overkill for the job. C919 is just crawling along as a program because it’s still brand new and heavily western based it would take time for the production like to shift to a more indigenous capacity. ARJ doesn’t seem suitable for the job due to the tail structure.
Bombers could be converted but are inefficient for such.
