Which of the following best describes the role of the UN in international relations?

The role of the United Nations (UN) in international relations is best described by the option that emphasizes facilitating peaceful negotiations. The UN serves as a global platform where member states can come together to address conflicts, promote dialogue, and seek out peaceful solutions to disputes.

This mission is rooted in the UN's founding principles, which prioritize diplomacy and cooperation among nations to prevent conflicts and foster sustainable peace. Through various bodies, like the General Assembly and the Security Council, the UN actively engages in mediating discussions, offering a neutral ground for negotiations, and supporting peace processes, as seen in peacekeeping missions and conflict resolution initiatives.

While regulating global trade, setting international economic policies, and enforcing military actions are important aspects of international relations, these roles are not central to the UN's primary mission, which is focused on maintaining international peace and security through peaceful means. Thus, the correct option captures the core function of the UN in promoting diplomatic resolutions in global affairs.
