Not really. Combine Chapter 84/85/90 exports from China and Japan. Even 84/90 if you want to remove the distortive effects of electronics assembly. China is still larger than Japan has been larger for a few years.Fair enough if that's what you're referring to as scientific metrics. I would consider Japan to have more high technology exports than China though but that's very quickly closing.
Different principles of physics as in the EUV method involves different physics compared to DUV for example. No matter how good China is at DUV lithography, it isn't the equivalent of EUV is what I mean. It's like training very hard and being very good at high jump when you need to compete in a long jump competition. Hence different. The evidence it's different is self apparent in that China has yet no solution to EUV.
It's as simple as bouncing light off mirrors just like a turbofan is as simple as compression air and lighting some fuel with it. Much easier said than understood and even harder to actually do.
On EUV, agreed, it's not the same but the underlying principles of excimer lasers and optics still apply. Doing DUV gives you skills that make EUV easier and I believe a few months ago, someone posted something about the CAS EUV prototype
