Xi made the remarks when holding talks with Russian President Vladimir Putin, who is on a state visit to China, Xinhua reported.
Xi pointed out that renewed fighting should be avoided, and most importantly, negotiation should continue.
An early end of the conflict will ease disruptions to the stability of energy supply, the functioning of industrial and supply chains and the international trade order, Xi said.
"I have put forward four propositions on safeguarding and promoting peace and stability in the Middle East to further build international consensus, and help deescalate the situation, end hostilities and promote peace," Xi added.
