What did we actually expect?
This is nothing at all new. Western countries have courted despotic, anti democratic, or impoverished countries for centuries where it benefited them. Whether they gained access to enormous markets, cheap (or free) labour or untapped resources they certainly prospered.
There may be some legal recourse but the fact is that any victory may end up coming in spite of the law.
The "we were just obeying the law" or "it was the way times were, back then" defense can only be run so far in the court of public opinion before it starts having real impact on the bottom line.
The congressional committee is going to be about as much use as a lit match in a snowstorm but the "dissident's" civil suit should result in a settlement. Sadly, whether it is holocaust survivors suing Swiss banks and German car makers, or Chinese suing American dot-coms the outcome will always be tailor made to produce the maximum benefit at the minimum cost from the point of view of the corporation. The victim will get his payday and it may well make him richer than his wildest dreams but moral or legal justice will get nothing.
In the end businesses will continue to engage with whomever it benefits them to, and will do so right at the bleeding edge of the law. It is their duty to their shareholders and unless their shareholders add to their responsibility a requirement for ethical and fair trading that can temper the drive for profits and growth then the corporations will continue along their path - perhaps factoring the odd lawsuit into their earnings projections.. just in case.
