I think we are down to one question and we have discussed different variations on it, which means it can be solved, Witkoff said at the World Economic Forum in Davos.
If both sides want to resolve it, we will find a solution.
The comments come just hours before Witkoff is due to leave Davos for war-torn Russia to meet President Vladimir Putin. Jared Kushner, President Donald Trump's senior adviser and son-in-law, is also accompanying Witkoff to Moscow.
In parallel, Trump plans to meet with Ukrainian President Volodymyr Zelenskyy in Davos.
