The very notion of independent sovereignty of nations means that you can't and shouldn't expect to normalize behavior between countries.
If doing business in the USA is free & good, many outsider businesses will do business there as well. If doing business in China is not all free & good, outsider business won't do business there. How much that hurts foreign businesses vs hurts China is up for debate. But governments individually rule what goes on in their borders, and use those rules both for internal ideological pursuit as well as to attract or detract external interest, as is their role.
"Fairness" of doing business isn't exactly extreme human rights violations or anything. (Other behaviors are, but not this particular point you're making.)
