Foreign relations refer to the way countries interact with each other. This includes forming alliances, negotiating trade agreements, and addressing global issues like climate change. Countries work together to promote peace and security, often through organizations like the United Nations. Diplomacy is a key part of foreign relations, where representatives, such as ambassadors, communicate and negotiate on behalf of their nations. Good foreign relations can lead to economic benefits, cultural exchanges, and stronger ties between nations, while poor relations can result in conflicts or trade barriers.
