Why is international cooperation in the field of non-traditional security necessary?

The threat of non-traditional security issues to all countries in the world is imminent, so the research on how to deal with non-traditional security issues has been put on the agenda. International cooperation is the key to deal with non-traditional security issues. Non-traditional security issue is a transnational issue in itself, which can be transformed with traditional security issues and easily infect each other before the country. Countries can only obtain relative benefits through competition, and cooperation can bring absolute benefits. Countries should solve non-traditional security problems through consultation and cooperation.
