"The comparison to the European Union is ridiculous. The European Union is an economic union in which the member states have ceded sovereignty," Mr. Mills said. "That is exactly not what the SPP is about. The U.S. is a sovereign country, Canada is a sovereign country and Mexico is a sovereign country."
Commerce Department spokesman Richard Mills said, "The SPP is merely a mechanism for the three countries to coordinate and try to reduce red tape and work on issues, whether it's border issues, security or health security."
