well naturally it's either try to rationalize it as "stealth isn't important" (in layman's terms), or, accept that stealth is important but suggest that the military they've portrayed as their primary competitor doesn't actually have stealth capabilities.
Considering how much the rest of the world is moving onto stealth, the former option is obviously out of the question, so the latter is really the only path left.
Of course they can detect them. The only meaningful question would be at what range.
Only USAF is going head down into Stealth business, with replacement of whole combat fleet as a goal. Even China(steady believer as it seems) goes for a mixed fleet.
Among all producers, only Russia went to drop existing fighter program for a stealthy replacement. Funny enough.
All others maintained their own, even if they clearly had a chance to do otherwise.
(at least for France it isn't a secret).
On the contrary, there are quite a few new programs with limited stealth objectives. They clearly concern themselves with signature reduction, but only reduction(KFX).
What's even more curious is what all a2a weapon development doesn't concern itself with stealth all that much. No Anti-stealth developments from early 1990s are here.
No dual-mode seekers, like on aim-152. No super-AWACS (well, a-100 conceptually is simillar, but it lost all its "super" part).
Only more and ever more capable AESA(PESA) radars and IRST. Both predate stealth and have a much wider usage.
China still has like 5 times the MK2s they've got, so they probably should stop dancing
.If J-20 is operating on Tibetan Plateau, it's for high altitude/cold climate testing/certification/development of special operating procedures. As such, it probably is operating with radar reflector active, at least most of the time, as there is really no operational reason for stealth. In fact, even when it's operating elsewhere in China in non-combat (simulated or otherwise) roles/exercises, the radar reflector is probably on, because stealth aircraft is actually a navigational hazard for both civilian and military aircraft due to the risk of collision.

Another thing that crossed my mind regarding the Su-30MKI detecting the J-20. PLAAF may have been deliberately testing the passive sensors of the J-20 near the Indian border. There is no risk of radar emissions on part of the PLAAF. The F-22 has the AN/ALR-94 and the F-35 has the AN/ASQ-239. The USAF has mastered the usage of the these systems. By purely using these passive systems, the aircrafts processing units provides an attack plan to the pilot. They constantly use this to sneak up on their aggressors. PLAAF maybe testing such system of the J-20 near the Indian border. When does the passive system pickup the IAF airborne and ground systems before the J-20 gets detected. PLAAF maybe testing how well the processing system map out attack plans against an adversery. I would say one way to do that is actually fly a J-20 with a luneburg lens near the Indian border and let the IAF take the bait. PLAAF not only picks up emissions/signatures of their adversery, they can also test how well the J-20 provides pilots with attack plans. I think, there is no offcial info or satelite imegary that the J-20 operated in that area but I would be surprised if they didn't. I mean, just fit nice big luneburg lens and fly the J-20 near the Indian border .

If you're already detected, it won't work this way.
Btw, are there any indications what j-20 self-defense suite is f-22 - like in its ideology?
Wrong. China wants new full stealth drones, full stealth carrier fighter, full stealth strategic bomber, full stealth attack/strike plane, full stealth 6th gen (assumed unless photonics radars make is pointless in decades time). I would say that is moving whole fleet towards stealth since all new platforms are/ will be full stealth. Current mixed fleet of non stealth is either old planes manufactured years before stealth or J-10C, J-15, and J-16 all of which have no current replacement programs. So your logic fails here. When there is a replacement for single engined fighter like J-10, it may be stealth. J-15 has no replacement either (J-31 or J-20 on carrier is nowhere to be seen so still years away but carriers are here and J-15 has great range and load capacity once CATOBAR carriers come so even with stealthy replacements, J-15 is pretty useful). J-16 is a strike fighter with no current replacements on the horizon. We haven't seen JH-xx so who knows if it can turn as well as J-16 -> determines role.
Europe is moving to F-35. That's full stealth. Airbus is looking into a full stealth program that "replaces" typhoon.
I would say this is convincingly in the favour of stealth since literally EVERYONE with the ability and money is moving to full stealth fleet. Contrary to what you are saying. The nations without this ability can only badmouth the others and make up excuses and dodgy articles. It's hilariously pathetic for them. If you suck, just admit it to yourself and others. Others usually don't care. Lose the ego and some of these nations may be able to do what East Asian nations managed to do in the last half century and actually identify problems, work actively and improve. All journeys start with a single step. Ignore those who laugh and mock. But I suppose some people are happy with their MKIs and MK2s and would rather sit on their hands while the rest of the world improves.

Why put passive sensors through this test? It's not like MKIs, Mig-29s, Mirage-2000 etc are LO visually or thermally (in fact I bet their signatures are accurately determinable and well known by now). PLAAF can do everything you listed in the comfort of home training and testing with their huge range of fighters and drones. No point risking yet another diplomatic problem.
