All I can say is that in 25 years of living in and travelling all over China, I have never come across mustard sauce as a condiment. I can't say there is isn't a restaurant somewhere dishing it up.
Not one of my local supermarkets (or any other supermarket I've seen) has mustard on its shelves.
I just did a quick search of the largest online shopping site and there is nothing Chinese. Dijon, American and Wasabi-type stuff as I mentioned.
P.S. I've never seen mustard served in Chinese restaurants in Europe, either. It seems to be American.
