It seems like the "of" does it more than anything. It parallels organizations like "Department of Defense" and "Federal Bureau of Investigation": some generic noun to represent that it's an organization of people, "of," and then an abstract noun that gives the organization a purview that's universal or total in scope. Most organizations that have the audacity to do this have a monopoly on the use of force behind them.

The CoC, of course, is itself in the business of government: trade its governmental access and leverage to businesses in exchange for large cash grants.
