Ban, who arrived in Kuwait City late yesterday, was to meet delegates from the Iran-backed rebels and the Yemeni government in a joint session on Sunday, according to a UN spokesman.
UN-backed talks between the Shiite Huthi rebels, who have seized control of large parts of the Arabian Peninsula country, and President Abedrabbo Mansour Hadi's government have failed to achieve a breakthrough since starting in Kuwait on April 21.
UN special envoy Ismail Ould Cheikh Ahmed has urged both sides to make concessions to end the conflict, which has cost more than 6,400 lives since March 2015 and displaced 2.8 million people.
But the Yemeni government is insisting the rebels withdraw from all territory they have seized since 2014 and hand back control of state institutions ahead of any political settlement.
