In T.D. 97-81, the Customs Regulations were amended to reflect the imposition of import restrictions on certain archaeological material from Guatemala. These restrictions were imposed pursuant to a Memorandum of Understanding between the United States and Guatemala (the MOU) that was entered into under the authority of the Convention on Cultural Property Implementation Act in accordance with the 1970 United Nations Educational, Scientific and Cultural Organization (UNESCO) Convention on the Means of Prohibiting and Preventing the Illicit Import, Export and Transfer of Ownership of Cultural Property. Recently, the United States Department of State determined that conditions continue to warrant the imposition of these import restrictions for a period not to exceed 5 years. The Governments of the United States and Mali exchanged diplomatic notes agreeing to extend the MOU. Thus, this document amends the Customs Regulations to reflect that the import restrictions currently in place continue, without interruption, for a period not to exceed five years from September 29, 2002. T.D. 97-81 contains the List of Designated Archaeological Material from Guatemala that describes the articles to which the restrictions and this extension of restrictions apply.
