Yemen's Ansar Allah, also known as the Houthis, takes two approaches to its relationship with Saudi Arabia. Informal negotiations between the two sides started first, paving the way for the Houthis to recently announce their desire for direct dialogue with Saudi Arabia in Riyadh, provided that it's public. At the same time, Houthi missiles and drones still penetrate Saudi airspace.
The informal negotiations between the Houthis and Saudi Arabia in Jordan were revealed in late September 2019. On June 13, the Houthis announced willingness to head to Riyadh and stop the Yemeni war that has been going on for over five years via a public dialogue with the Saudi-led Arab coalition on a comprehensive cease-fire.
