The purpose of a diplomatic envoy in international relations is to represent and advance the interests of their sending state abroad. Diplomatic envoys, including ambassadors and high commissioners, engage in negotiations, foster bilateral relations, and facilitate communication between governments. They are responsible for promoting peace and stability, addressing conflicts, and creating agreements on issues ranging from trade to security. Additionally, envoys often provide valuable insights to their home government regarding foreign perspectives and developments. Through these functions, diplomatic envoys play a critical role in maintaining effective diplomacy and international cooperation.
