Well damn. Yes. Though, now that I stop to think about it, the Pacific is kind of crazy in that the Western Pacific is in the Eastern Hemisphere and the Eastern Pacific is in the Western Hemisphere.
And now I have a headache.
This ain't the early Cold War anymore. While there are certainly some super-secret weapons platforms out there, a lot of military capability is deliberately communicated and even put on display because it deters conflict.
When the Soviet Union fell the Pentagon's priorities shifted from "World War 3 against the USSR" to "wars against countries with marginally effective air forces." So when the B-2 came online, it served the Pentagon's mission better to show it off. "Look at our invisible bomber. You really think crossing us is a good idea? Be a shame of bombs just fell out of an empty sky on you without any warning whatsoever."
China wants the US to know that it can launch stealth aircraft off of its carriers because that allows it to use its carriers to assert control of the Eastern Pacific. China doesn't regard war with the United States as inevitable. Consequently, it's interested in convincing the United States that a war in the Pacific isn't worth fighting. That means eroding American confidence in American strategic and technological dominance so Americans know that a conflict with China will be costly.
This is targeted directly at American isolationists: "do you really want your kid to die for Taiwan?"
As a historian the only caveat I'd advise there is that we are unlikely to see a long, drawn-out slog like WW2 again. Production capacity is great but the next Great Power war isn't likely to take place over years or even months. So China's technological edge is likely to matter but it's tempered with a willingness to stockpile and maintain systems which may never see use.
Doing that at limited production scale is one thing. Doing it at massive, "we're going to fight a serious war with this stuff" scales is another. China, like many authoritarian regimes, has shown itself to be dazzled by the propaganda value of wonder weapons. The CJ-1000, most recently, seems like a very impressive missile system but if it doesn't exist is sufficient quantity to turn the tide against American assets in theater it's just a waste of money.
Of course, China is also famously closed lipped so it's hard to tell. It might turn out that they have tens of thousands of those things. Probably not, but maybe.
If all the world's economists were laid end to end, we wouldn't reach a conclusion. -- William Baumol
