Key points:  With diverse transboundary links in environmental crimes increasingly prominent, there is a need to identify tools to enhance international or regional cooperation in order to strengthen forest enforcement.  Mutual legal assistance (MLA) has particular potential to facilitate cooperation across jurisdictions.  Provisions on dual criminality and predicate offenses often limit the scope for MLA on forest-related crimes, both within Indonesia and in partner countries.  Proactive establishment of bilateral MLA agreements could strengthen MLA use, including with countries where the financiers and traders often reside and bank.  Existing platforms provide opportunities to operationalize country commitments to international cooperation on environmental topics.
