Guyanav. Suriname is a case where the international tribunal has an opportunity to deal with the state responsibility issue in a maritime delimitation dispute. This paper examines the jurisdiction of the arbitral tribunal over Guyanese submission that Suriname was internationally responsible for violating its obligations under the LOS Convention, the Charter of the United Nations and general international law to settle disputes by peaceful means. And the arbitral tribunal made great contributions to the clarification of the obligations under Articles 74(3) and 83(3) of the LOS Convention to make every effort to enter into provisional arrangements and not to jeopardize or hamper the reaching of a final delimitation agreement.
