The US envoy charged with pushing for lasting peace in Yemen headed back to the region on Monday to build support for a fragile truce that's set to expire early next month. 

US special envoy for Yemen Tim Lenderking will visit Riyadh, Saudi Arabia, and Amman, Jordan, for discussions focused on “expanding, extending, and renewing the current truce agreement that will further the tangible benefits already reaching Yemenis and build towards a more comprehensive, inclusive peace process and permanent ceasefire,” the State Department said in a statement. 

Why it matters: Lenderking’s diplomacy follows President Joe Biden’s trip to the Saudi city of Jeddah earlier this month, during which he said Saudi Arabia agreed to extend and strengthen the truce. 

The truce between the Houthis and the Saudi-backed Yemeni government, which was announced in April and renewed for two months in June, marks the longest period of calm since the start of the conflict in late 2014. The fighting and resulting humanitarian crisis has killed nearly 400,000 people, uprooted millions from their homes and left the Arab world’s poorest country teetering on the brink of famine.
