Vanuatu undertook a Diagnostic Trade Integration Study ("DTIS"), which was validated in November 2007. Subsequently, Vanuatu benefited from one IF Window II project, to: provide legislative assistance to the Department of Customs to review the customs duties Act and related legislation, and to have a comprehensive update of the Act; support to WTO accession process; and entrepreneurship training to cooperatives. The National Implementation Unit ("NIU") was also established in 2007 under the IF Window II project. Under the EIF, Vanuatu with support from UNDP is developing a Tier 1 support to National Implementation Arrangements ("NIAs") project.
