Diplomatic ethics refers to the principles and values that guide the conduct of diplomats in the performance of their duties. Diplomatic ethics are an important aspect of international relations, as they help to ensure that diplomats act in a responsible and professional manner and that they uphold the values and interests of their governments and the international community.

Diplomatic ethics can include a range of principles and values, such as honesty and integrity, respect for the sovereignty and laws of other nations, and a commitment to promoting the common good. Diplomats are expected to act with tact and discretion in their interactions with other nations and to refrain from actions that might be perceived as interference in the internal affairs of other countries.

In addition to these general principles, diplomats are also subject to specific codes of conduct and guidelines that are set out in international agreements and by their own governments. These codes and guidelines can help to ensure that diplomats adhere to ethical standards in the performance of their duties.
