Signed in Geneva on April 21, 1961, this Convention, in parallel with the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, represents the main regional instrument on arbitration. The objective is to promote international arbitration as a valid dispute resolution mechanism in commercial matters between parties from different member states of the Council of Europe, harmonizing certain procedural aspects related to arbitration. Compared to the New York Convention, it regulates the procedural aspects of international arbitration in more detail, particularly concerning the initial phase of the procedure.
