“There are at least 100 systems of competition law in the world today. Some of these laws date back more than a century: the US, for example, enacted the Sherman Act in 1890. The competition rules of the European Union were adopted by the Treaty of Rome of 1957. The German Act Against Unfair Restraints of Competition was also adopted in 1957. Antitrust law in the United Kingdom began with the Monopolies and Restrictive Practices (Inquiry and Control) Act of 1948. The first competition law in Japan was the Act Concerning Prohibition of Private Monopoly and Maintenance of Fair Trade of 1947. Since the beginning of the 1990s, the number of systems of competition law has proliferated. Competition law is now in place in all six continents, and in all kinds of economies—large, small, continental, island, advanced, developing, industrial, trading, agricultural, liberal and post-communist. Following are various sources of information on the countries that have adopted systems of competition law.”
