It is unacceptable for the United States and Israel to launch strikes on Iran during the Iran-U.S. negotiations, Chinese Foreign Minister Wang Yi said during a phone conversation with his Russian counterpart Sergei Lavrov on Sunday.

Wang, also a member of the Political Bureau of the Communist Party of China Central Committee, said that it is also unacceptable for them to openly kill the leader of a sovereign state and encourage government transfer, adding that these actions violate international law and basic international relations.
