International crime derives from which of the following sources?

International crime is primarily defined and governed by global treaties and conventions. These legal frameworks establish shared definitions of various international crimes, such as genocide, war crimes, and crimes against humanity. By creating a standardized set of laws that member states agree to be bound by, these treaties facilitate cooperation in the enforcement of international law across different jurisdictions.

The role of global treaties and conventions is crucial because they offer a legal basis for prosecuting individuals for crimes that transcend national borders, requiring a unified international approach to justice. For instance, the Rome Statute of the International Criminal Court serves as a key legal instrument outlining the provisions for the prosecution of serious international crimes.

While national legislation can implement and enforce these international laws within a country's jurisdiction, it is not the primary origin of international crime. Regional accords may address specific issues pertinent to certain geographical areas but do not have the same universal applicability as global treaties. Local customs and practices, while important in cultural contexts, do not establish legal norms for international crime and are generally insufficient for prosecution of crimes recognized on a global scale.
