It can still be racist if its counter-factual and driven by a dismissal of China itself. In fact it can be racist even if the same person accepts e.g. Japan, as Japan and Korea faced the same dismissals in the 60s to 80s (as copiers, second rate quality places, corrupt states, etc) before being accepted.
The fact is that China has been trusted by almost all major global companies for their manufacturing, so China can't be said to be a "low trust country" as a blanket statement.
Of course China can have low trust businessmen or low trust state officials, or they might be losing trust now (with the trade war and co).
But for decades they have had the trust of almost all western companies. Enough trust that they have been doing their manufacturing there (even exclusively there) for 2+ decades.
