The term "international stage" refers to a global platform or arena where events, actions and interactions between countries take place. It is used metaphorically to describe situations in which nations come together to discuss, negotiate, compete or cooperate on issues of mutual interest or concern. This can include international organizations such as the United Nations, economic forums like the G20 summit, sporting events like the Olympics and cultural exchanges between countries. The phrase implies that these activities involve multiple nations working together to achieve common goals, and are therefore more significant than domestic affairs alone.
