United States–China security cooperation

United States and China are two countries that are working to be friends and not enemies. They want to work together to keep the world a safe place. Security cooperation is like two friends who agree to help each other out if something bad happens. For example, if one friend gets lost, the other friend will help find them. In this situation, the United States and China are working together to make sure that they help each other and keep their countries safe. They are talking and sharing information about things that might be dangerous, like weapons or computer hacks. They are also making rules about how they can work together, so that things don't get confused. This way, they hope to be a really good team that can protect the world.
