Following the Stockholm Agreement, reached in Sweden on 13 December 2018, between the Government of Yemen and the Houthis under the auspices of the Special Envoy of the Secretary-General for Yemen Martin Griffiths, the Security Council in its resolution 2451 (2018) authorized the establishment and deployment, for an initial period of 30 days, of an advance team to begin monitoring and to support the immediate implementation of the ceasefire and redeployment of forces from the city of Hudaydah and the ports of Hudaydah, Saleef and Ras Isa.

By the same resolution, the Security Council requested the Secretary-General to submit proposals before 31 December 2018 on how the United Nations will fully support the implementation of the Stockholm Agreement, including substantive monitoring of the ceasefire and the redeployment of forces. It also mandated the United Nations to chair the Redeployment Coordination Committee (RCC) set up to oversee the ceasefire and the redeployment of forces. The Secretary-General appointed retired Major General Patrick Cammaert (The Netherlands) as the Chair of the RCC. Together with an advance team, Mr. Cammaert arrived in Hudaydah on 22 December 2018 and commenced the provision of UN support for the implementation of the Stockholm Agreement.

On 16 January 2019, the Security Council unanimously adopted resolution S/2019/2452 authorizing the establishment of a new Special Political Mission, the United Nations Mission to support the Hudaydah Agreement (UNMHA).
