Vienna Convention

The Vienna Convention on Diplomatic Relations of 1961 is an international treaty that defines a framework for diplomatic relations between independent countries, aiming to facilitate friendly relations among governments through a uniform set of practices and principles. The convention codifies diplomatic immunity, granting diplomatic missions privileges that enable diplomats to perform their functions without fear of coercion or harassment by the host country. It is a cornerstone of modern international relations and international law, almost universally ratified and observed, and considered one of the most successful legal instruments drafted under the United Nations. The convention was adopted on April 18, 1961, and first implemented on April 24, 1964, and has 193 state parties, including all UN member states except Palau and South Sudan, and the UN observer states of the Holy See and State of Palestine.learn more on wikipedia
