Cooperation Between Countries in the Enforcement of International Criminal Law as an Effort to Combat Transnational Crimes That Threaten World Peace

Abstract

Transnational crime is a form of crime that develops along with increasing globalization and technological advancement, thus posing a threat to world security, order, and peace. The characteristics of crimes that cross national borders mean that their enforcement cannot be carried out based solely on national law, but requires the role of International Criminal Law and cooperation between countries. This research aims to analyze transnational crimes from the perspective of International Criminal Law and examine the importance of cooperation between countries in supporting law enforcement against these crimes. This research uses normative legal research methods with a legislative approach and a conceptual approach. The data used were in the form of primary, secondary, and tertiary legal materials obtained through literature studies, then analyzed qualitatively descriptively. The results of the study show that International Criminal Law has provided various legal instruments, such as the United Nations Convention against Transnational Organized Crime (UNTOC) 2000, the 1948 Genocide Convention, and the 1998 Rome Statute, as the basis for law enforcement against transnational crimes. However, the effectiveness of law enforcement is highly dependent on cooperation between countries through the Mutual Legal Assistance (MLA) mechanism, extradition, information exchange, and coordination with international organizations such as INTERPOL, UNODC, and the United Nations. Therefore, strengthening international cooperation is an important factor in increasing the effectiveness of international criminal law enforcement to combat transnational crime and realize world security and peace.
