Its main functions include representing the nation in diplomatic matters, negotiating treaties, and promoting trade and investment abroad. The DFA also provides assistance to citizens traveling or living overseas. In addition to diplomatic activities, the DFA works to enhance global cooperation on issues such as security, human rights, and environmental protection. It often collaborates with international organizations like the United Nations and engages with other countries to address global challenges and foster peaceful relations.
