What was discussed in the U.S.-Russia talks in Riyadh regarding Putin and Trump?

During the U.S.-Russia talks in Riyadh, conditions for a potential meeting between Putin and Trump were discussed. According to Putin's aide Yushakov (Ushakov), the discussions addressed the framework for a possible summit between the two leaders, though it appears the meeting is unlikely to happen in the immediate future. Yushakov also indicated that Putin will be the one to decide when talks with the United States regarding a peace deal for Ukraine will begin. This suggests that while diplomatic channels remain open, the timing of substantive negotiations on resolving the Ukraine conflict remains under Russian consideration.
