This post comes in light of deteriorating diplomatic relations between India and Pakistan. Both have dismissed multiple members on one another’s diplomatic missions in their countries. Even though it seems to be more of a tit for tat diplomacy, this could result in great harm to diplomatic relations between the two countries. This is not only because of repo career diplomats take years to make in the governance and political system of the foreign country, but also due to legal consequences that flow. In this post, we try to bring to you basic international treaties that govern diplomatic relations between two countries. Perhaps these laws are followed by almost all the sovereign countries in the world and in 1992, UN general assembly, by a resolution, gave Vienna convention on diplomatic relations, 1961 status of customary international law. This would mean that in international context it is binding even without a nation state explicitly submitting to its jurisdiction.
