The International Trade Centre (ITC) is a subsidiary organisation of the World Trade Organisation (WTO) and the United Nations Conference on Trade and Development (UNCTAD) and provides trade-related technical assistance, primarily to developing countries. ITC has had several projects with Jamaica over the years.
