In 2018，the Saudi coalition and the Huthis caused the Hodeida crisis. With the mediation of UN Special Envoy Martin Griffiths，and the pressure imposed by the US against Saudi Arabia，the Huthis and the Hadi Government reached the Stockholm Agreement in late 2018. However，the three main issues of the agreement—prisoner swap，the Hodeida agreement and the Taiz understanding—have made limited progress. In addition，the conflicts in the other fronts have intensified，and they struggled for legitimacy terribly. The lasting Yemen war causes a large number of casualties and serious humanitarian crises in Yemen，and worsens strategic competition and hostility among the Gulf States. Moreover，terrorism，environmental damage and gender security caused by war will have long-term effects on Gulf security. It is still difficult to achieve comprehensive peace in Yemen. The Yemeni people and the international community need to work together to build a comprehensive framework for solving the problems of Yemen.
