TBH what is he expected to say? "Sorry, but our guys don't stand a chance against this beastie"?
Also, it never ceases to amaze me why some Merkins think it's a some kind of burn to say China "stole" their technology. I say, well done China's spies, you saved your country tens or hundreds of billions of $$ in development costs! It also suggests China is at least on a par with US tech. Anyway, most military technology is "stolen" somewhere down the line, I don't think there's a rule of war requiring one side not to use equipment it copied or captured from the other!
Taking the comment on its own terms:
"
I don’t think that it’s a dominating aircraft at this point, compared to what we have [in terms of stealthy and ],"
I'm not aware of any PLAAF claim that J20
would "dominate" F22/F35, it would probably stand a pretty good chance against them though, which is why the General went on to talk about training, integration, allies, etc. Also the Chief of all USAF (not just PACAF) said that the early block F22s were being retired at least in part because they weren't competitive with J20.
Anyway, "not dominant" is a fairer assessment than the "semi-stealth" sort of assessments we've seen in the past. And "at this point" means there is potential for J20 to become a "dominating aircraft" in the future (maybe pretty soon with WS15 and other imporvements).

Our technology is the best. Their technology, that they stole from us, sucks."
