Terrorism seriously endangers world peace and security. In order to achieve the goal of effectively combating international terrorism, we must promote the establishment of a multi-level model of anti-terrorism cooperation. The current legal models of international counter-terrorism cooperation mainly include global counter-terrorism cooperation, regional counter-terrorism cooperation and bilateral counter-terrorism cooperation. Global counter-terrorism cooperation led by the United Nations is the most important form of counter-terrorism cooperation. The UN has set up a Counter-terrorism Committee and a series of treaties. The United Nations demands that States should prevent and stop the financing of terrorist ACTS; Criminalizes any person or thing that, by any means, directly or indirectly, provides or raises funds for terrorist activities; (b) Immediately freeze the assets of individuals and entities that facilitate, finance or participate in terrorist ACTS; The provision of any funds and financial assets and related services to individuals and entities assisting, financing or participating in terrorist ACTS is prohibited. Regional counter-terrorism cooperation refers to the cooperation between geographically adjacent countries to combat terrorism, which is an important part of international counter-terrorism cooperation. The main regional anti-terrorism cooperation organizations are: Association of Southeast Asian Nations, South Asian Association for Regional Cooperation, European Union, Organization of American States, Shanghai Cooperation Organization. Bilateral anti-terrorism cooperation refers to the cooperation between two parties in order to form a joint anti-terrorism force. Bilateral cooperation can be between states or between states and regional organizations. Bilateral cooperation in flexible and diverse forms is also an important form of counter-terrorism cooperation.
