States Parties shall promote training and technical assistance that will facilitate extradition and mutual legal assistance. Such training and technical assistance may include language training, secondments and exchanges between personnel in central authorities or agencies with relevant responsibilities. 4.

Article 30 Other measures: implementation of the Convention through economic development and technical assistance 1. States Parties shall take measures conducive to the optimal implementation of this Convention to the extent possible, through international cooperation, taking into account the negative effects of organised crime on society in general, in particular on sustainable development. 2.
