Proxy diplomacy is a form of diplomacy where one country or entity delegates the task of negotiating with another country to a third party. In proxy diplomacy, the third party acts as an intermediary or go-between, conveying messages and negotiating on behalf of the original party.
Proxy diplomacy can be used for a variety of reasons, such as when two countries do not have formal diplomatic relations, when there is a lack of trust between the parties, or when one or both parties want to keep their involvement in negotiations secret. Proxy diplomacy can also be used as a way to bring parties to the negotiating table who would otherwise refuse to talk to each other.
Examples of proxy diplomacy include peace talks between Israel and Palestine mediated by the USA, negotiations between North and South Korea mediated by China, and talks between the USA and Iran mediated by Oman.
