Every country that moves up the value ladder goes through that phase. First the British looked down on the Germans and the US, then the three of them on Japan, then on Korea and Taiwan, then China. Now I guess it's mostly Malaysia and Thailand; the 'Chinese = low tech' stigma is mostly a boomer thing.

Chinese manufacturers probably have it slightly easier because China itself is such a huge market, so most of their sales would be domestic. But I wonder if people from Shenzhen or Shanghai will look down at products made in, say, Hebei.
