The chapter gives a detailed account of inter-state corporations in combatting cybercrime and its limitations. The chapter situates the current negotiations of a new legal instrument to counter cybercrime within the UN’s historical framework of efforts to enhance co-operation against general organised crime and cybercrime. In particular, it analyses the main issues that have held back progress in enhancing co-operation. It then proceeds to examine the current negotiation process and the prospects for effective co-operation once the negotiations come to an end, highlighting the potentially impactful legal implications of the work of the UN ad hoc committee on cybercrime.
