In an ideal closed system, all three must work together in order to create a good prosperous environment for trade to develop. In actual cases each firm makes its own reward and benefit analysis. When it comes to China, foreign firms have taken the risk of more ambiguous legal protection in order to reach out to a market of 1.3 billion.
And let's not forget ambiguous legal environment has also created massive profit for foreign firms. For example GSK made billions taking advantage of corruption in China until it was caught and fined only 489 millions.
Taking advantage of corruption is not a sound business model. Sooner or later chickens will come home to roost. The problem is there is a price for the country to be had and the bill might be shocking.
