Stealth is not boolean. Supercomputers with huge antenna arrays will not fit into aircraft. Aircraft radar will not fit into the small-diameter head of an air-to-air missile. Becoming aware of a target is not the same as tracking a target. Occasional detection is not the same as reliable detection. China being able to do something against stealth does not mean that every other country can do the same thing. BTW, there are motives to both hide and exaggerate military capability. Perhaps several countries have what China claims to have, but China itself doesn't have it.
