Ambassadors hold primary responsibilities that include representing their home country, promoting diplomatic relations, and protecting the interests of citizens abroad. They act as liaisons between governments, facilitating communication and negotiation on key issues like trade, security, and human rights. Additionally, ambassadors work to strengthen bilateral ties and engage in public diplomacy to foster mutual understanding. They also report back on political developments and potential challenges in their host country, providing critical information that informs both foreign policy and decision-making at home.
