One of the notable trends in recent years has been the increasing importance of the cross-border supply of services. This is occurring in a large number of services sectors, both through the partial substitution of services earlier supplied by the commercial presence of foreign companies or by moving natural persons, and through trade in newer services such as telemedicine and research and development. The other dynamic trend is the growth in offshoring, with developing countries as important participants. These trends provide huge scope for developing countries to exploit their comparative advantages in labor-intensive services without displacing substantial labor in developed economies, at the same time adding to efficiency gains and cost reductions in the latter. The further opening of markets for cross-border services, by providing the necessary boost to the global growth engine, could become a win-win situation for all.

Current policy with regard to the cross-border supply of services, both in developed and developing nations, seems to be more liberal than reflected in current GATS commitments or offers submitted in the Doha Round. The liberalization of the cross-border supply of services has featured prominently not only in current WTO negotiations, but also in recent preferential trade agreements between various countries. The trend in many of these bilateral negotiations appears to be toward the binding of the actual status quo. The PTA context seems unsuitable for establishing the grounds of a truly open global environment for the supply of services on a cross-border basis, however.
