This publication aims to assist developing country negotiators in their approach towards assessment of trade in services. First, it explains why assessment is of particular importance to developing countries; second, it provides some preliminary ideas on the appropriate nature of an assessment; and finally, this note offers some recommendations to operationalise paragraph 14 of the negotiation guidelines. These suggestions and recommendations are made with a view to initiating a discussion amongst WTO Members, the Secretariat and civil society on the need and relevance of conducting an assessment of trade in services and its liberalisation.
