Reuters. China's Foreign Minister Wang Yi told Russia's Foreign Minister Sergei Lavrov on Sunday that attacks by the United States and Israel on Iran during U.S.-Iran negotiations were "unacceptable", according to state news agency Xinhua.
Wang said the "blatant killing of a sovereign leader" and the incitement of regime change were unacceptable.
China is calling for an immediate cessation of military action, a return to dialogue and negotiations as soon as possible, and joint opposition to unilateral actions, the minister said.
China's ministry on Saturday expressed concern over the strikes and called for an immediate ceasefire, urging all sides to avoid escalation and to resume dialogue and negotiation.
It said Iran's sovereignty, security and territorial integrity should be respected.
In a commentary on Sunday, China's state-run Xinhua news agency criticised the attack, calling it "brazen aggression against a sovereign nation" and "power politics and hegemony".
Xinhua said Washington's use of military coercion was a "flagrant violation" of the purposes and principles of the United Nations Charter and a departure from "fundamental norms of international relations".
