"China has always opposed the use of force in international relations," Chinese foreign ministry spokesman Geng Shuang said at a daily press conference. "We urge the relevant sides, especially the United States, to remain calm and exercise restraint to avoid further escalating tensions."

Shuang said the international community must respect Iraq's independence and territorial integrity. 

He urged both sides to abide by the principles of the U.N. charter and the "basic norms of international relations."

Secretary of State Mike Pompeo tweeted on Friday morning that he spoke with "Chinese Politburo Member Yang Jiechi to discuss @realDonaldTrump 's decision to eliminate Soleimani in response to imminent threats to American lives. I reiterated our commitment to de-escalation."
