The move seriously violates the United Nations Charter and worsens tensions in the Middle East, the ministry said in a statement on its website.
China urged parties to the conflict, especially Israel, to cease attacks as soon as possible and begin dialogue and negotiations, the ministry said.
Elsewhere, United Nations Secretary-General Antonio Guterres warned that the U.S. strikes on Iran represent a dangerous escalation in an already volatile region, posing a serious threat to global peace and security.
“There is a growing risk that this conflict could rapidly get out of control – with catastrophic consequences for civilians, the region, and the world,” Guterres said in a statement as reported by Reuters.
“At this perilous hour, it is critical to avoid a spiral of chaos. There is no military solution. The only path forward is diplomacy. The only hope is peace,” he said.
The European Union’s chief diplomat Kaja Kallas urged “all sides to step back, return to the negotiating table and prevent further escalation,” while stressing Iran must not be permitted to develop a nuclear weapon. EU foreign ministers will discuss developments in Iran on Monday, she said.
