China is “deeply worried” about Israel’s military operation against Iran that has escalated tensions in the Middle East, President Xi Jinping said on Tuesday.

“All parties should work to de-escalate the conflict as soon as possible and prevent further escalation of tensions,” he said during a meeting with the Uzbek president in Kazakhstan, Xinhua reported.

China is ready to play a constructive role in restoring peace and stability in the Middle East, he added.

China has also accused President Donald Trump of “pouring oil” on the mounting conflict between Iran and Israel, after the US leader warned Tehran residents to “immediately evacuate”.

Asked about Trump’s remarks, Chinese foreign ministry spokesman Guo Jiakun said: “Fanning the flames, pouring oil, making threats and mounting pressure will not help to promote the de-escalation of the situation, but will only intensify and widen the conflict.”

“The Chinese side calls on all relevant parties, especially countries with special influence on Israel, to shoulder their responsibilities, take immediate measures to de-escalate tensions, and prevent the conflict from expanding and spreading.”
