Considering that the prevention of corrupt practices and transfer of assets of illicit origin and the return of such assets to the countries of origin have not been adequately regulated by all national legislations and international legal instruments,
考虑到并非所有国家立法和国际法律文书都已对防止腐败行径及转移非法来源资产的活动以及将这些资产返还来源国的问题加以充分管制，
