What is a transparent trade and investment environment?
One in which investors have visibility into the financial bona fides of those enterprises they might invest in.
International investors, i.e., those with the serious money, i.e., those from capitalist economies, have to have real financial and organizational information on potential investements, and they have to have confidence that those data are real.
This can happen only when there are existing norms for business relationships, and those norms resemble those in the developed world.
And that can happen only where there is a semblance of criminal and civil law.
