Which of the following is not a purpose of the United Nations?

The role of the United Nations encompasses various objectives aimed at fostering cooperation among countries, ensuring international peace, and addressing global challenges. One of the fundamental purposes is to promote international peace and security, as well as to encourage disarmament among member nations, thereby reducing the likelihood of conflict and fostering stability.

While the UN does facilitate diplomatic relations and dialogue among nations, granting diplomatic recognition and exchanging ambassadors is not explicitly a purpose outlined in the UN's charter. This diplomatic function is typically the responsibility of individual nations and their foreign ministries, rather than a specific objective of the United Nations as an organization.

The UN's focus on peace, security, and disarmament reflects its commitment to preventing conflicts and ensuring a collaborative approach to international issues. Therefore, while diplomatic recognition is a crucial element of international relations, it does not fall under the primary roles of the UN. Additionally, expediting global trade agreements is more aligned with the functions of organizations dedicated to economic collaboration, rather than the core mission of the United Nations.
