State C is a WTO member state and a party to NAFTA. It has made no specific agreements under either GATS or NAFTA as to its road transport sector. Now, two freight companies, one from State D (a WTO member state) and one from State E (a party to both the WTO and NAFTA), wish to provide overland freight transportation services in State C using trucks operating out of terminals in their states of establishment. May they do so? If so, to what extent? Explain.
