Arbitration has been used for centuries, including in antiquity, for the resolution of disputes between states and state-like entities.[20] After a period of relative disuse, Jay's Treaty between the United States and Great Britain revived international arbitration as a means of resolving inter-state disputes. The 1899 and 1907 Hague Conferences addressed arbitration as a mechanism for resolving state-to-state disputes, leading to the adoption of the Hague Conventions for the Pacific Settlement of International Disputes. The Conventions established the Permanent Court of Arbitration and a rudimentary institutional framework for international arbitration of inter-state disputes.[21] In recent years, international arbitration has been used to resolve a number of disputes between states or state-like entities, including Eritrea v. Yemen,[22] the Abyei Arbitration,[23] the OSPAR Arbitration,[24] and the Iron Rhine Arbitration.[25]
