Tricky question no one really knows. US and Japan have more military technology sophistication than China even though we are catching up. The main stealth advantage which US hold is part of its breaking into the 5th generation and its philosophy of how to fight the type of war it wants to fight. In reverse position defending from attack, China's aim was to counter stealth as much as possible and the conclusion was it is impossible to do well because like fighter vs SAM problem, the SAM always lose because the fighter has the choice of how to fight. Simplifying it but this is the same with stealth problem. The reason for more stealth fighters and focus on stealth fighters is because it works so well.
Some ground radar and we can call methods of defeating stealth involve integration of multiple sensor nodes based on different types with purpose within this network. For example there will be one particular type of frequency placed here and in other specific locations they need different types. In a combined effect, with what some long ago already said in public as software solution to perform optimizing of this effort and machine learning to keep improving the algorithm, it is possible to detect stealth from long enough away. The problem is the fighters require networked engagement which is not easy to do with such a large network. Between a ship and a fighter or AWACS and fighter is different to a whole network of radars with many layers of algorithms to fighter and then to missile.
Both the fighter and missile cannot detect until too close. The network cannot move around quick enough and is always requiring defending. This solution is good and works but you can see how it is not so useful. For now the best way of countering stealth is playing the same game. Until single radars and missiles can increase detection and engagement range to far enough, there is no easy way to deal with stealth.
Short range is still important but definitely less important than in the past unless electronic attack methods have not improved much which is quite unlikely. Now I think they can all suppress missiles signatures until very close and make the ability to avoid being shot much harder than it was previously.
