Regarding the May 29 editorial “Yemen on the brink”:

The United Arab Emirates, as a member of the Coalition Supporting Legitimacy in Yemen, is committed to and actively working with international partners to ensure the delivery of aid in Yemen.

The UAE has contributed $3.76 billion of relief aid to the Yemeni people since April 2015. The coalition is collaborating with the United Nations to ensure that humanitarian agencies can access the city of Hodeida and deliver aid during this critical time. The coalition’s efforts to open land, sea and air lanes to the country enables 1.4 million metric tons of imports into Yemen each month.

The UAE has driven out extremist forces from ­al-­Qaeda in the Arabian Peninsula and the Islamic State from areas they had taken over following the Houthi coup. These areas, as well as in Aden, along the Red Sea and in the other large swaths of the country liberated from Iranian-backed Houthi oppression, are far better off with improved security, public services and humanitarian assistance.

Ultimately, to guarantee that the humanitarian situation is resolved, a political resolution must be reached. The Houthis are the main obstacle to achieving peace under a legitimate government in Yemen. Prior to this past weekend’s visit to Sanaa by the U.N. special envoy for Yemen, the Houthis had refused any substantive engagement with the U.N.-led negotiations.

The parameters of peace must be agreed upon by the people, including the Houthis if they lay down their arms and engage in the peace plan. No stable state can exist while an armed vigilante militia occupies its ports and cities.

The coalition will continue to uphold international law and safeguard civilians while undertaking operations at the request of the legitimate government of Yemen.
