Earlier, Chinese President Xi Jinping said during phone talks with Russian President Vladimir Putin that the conflict in the Middle East is showing that the world has entered a new period of instability and dramatic change.
The Chinese president put forward some proposals, saying the top priority is to facilitate a ceasefire. He also called for efforts to ensure the safety of civilians and warned against indiscriminate use of force.
