With examples explain systematic tools of international relation?

Systematic tools of international relations include diplomacy, economic sanctions, and military alliances. For example, diplomacy involves negotiations and dialogue between countries to resolve conflicts, such as the Paris Agreement on climate change. Economic sanctions, like those imposed on North Korea, aim to pressure a state to change its behavior by restricting trade and financial transactions. Military alliances, exemplified by NATO, provide mutual defense agreements among member states to enhance collective security against threats.
