International policies are rules and agreements made between countries to manage their relationships and address global issues. These policies can cover a wide range of topics, such as trade, security, and environmental protection. For example, countries may create treaties to reduce carbon emissions and combat climate change, which involves cooperation among nations like the United States and China. These policies are important because they help maintain peace and stability in the world. By working together, countries can tackle challenges that affect everyone, such as pandemics or terrorism. International organizations, like the United Nations, play a key role in facilitating discussions and ensuring that countries adhere to these agreements.
