On that day, the three countries became the largest free market in the world – the combined economies of the three nations were $6 trillion and directly affected more than 365 million people. NAFTA was created to remove customs barriers for agriculture, manufacturing and services; Eliminating restrictions on investment protection of intellectual property rights. This should be done while respecting environmental and labour concerns (although many observers point to the fact that the three governments have been negligent in environmental and safety at work since the agreement came into force).
