The Interagency Task Force on Statistics of International Trade in Services (TFSITS) was formed at the request of the General Agreement on Tariffs and Trade (GATT) and UNCTAD to the Statistical Commission in 1994. The objectives of the Task Force were to elaborate the statistical requirements of the General Agreement on Trade in Services (GATS). A Manual on Statistics of International Trade in Services (MSITS) was published in 2002. An revised version will be presented to the UN Statistical Commission in 2009.
