The original comment did not say that China is distrustful because they are of a different race or that their race makes them inherently distrustful. I think shutting down any argument with "that's racist" is disingenuous. If we go by your logic you can say "that's racist" to any criticism of China.
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.
It’s the low cost of human capital, and now the realization of lost non-Chinese suppliers, that continues to keep China thriving.
One does business in China because it’s the only way (currently) to stay afloat.
And yes, corruption is inevitable in China because of its inconsistent rule of law and inability of dedicated journalists and grassroots movements to expose, uproot, and punish said corruption.
Edit: China is at a crossroads, but whether those in power will step-up to greatness and allow its greatest resource (its people) be more than puppets and slaves remains to be seen.
They also had a democratic process, a lawful system ( bias or not ) in place where many of these issues can be solved diplomatically.
Not the same of China, everything is tangled together. CCP.
