Russia has joined China in calling for a policy of non-interference in Iran's domestic affairs after a week of unrest has gripped multiple major cities and towns across the country in what started as protests over economic grievances, but which have since increasingly turned to riots and calls for President Rouhani and the clerical regime to step down, resulting in the deaths of at least 22 people, including at least one police officer who was shot dead.

In remarks given to Russia's TASS news agency Russian Deputy Foreign Minister Sergey Ryabkov expressly warned the US "against attempts to interfere in the internal affairs of the Islamic Republic of Iran," while stressing, "What is happening there is an internal affair, which attracts the attention of the international community." Russia's stance is similar to that of China's voiced previously on Tuesday. When asked about the Iran protests at a regularly scheduled press conference, China’s foreign ministry spokesperson Geng Shuang simply gave a one-sentence answer, saying, “China hopes that Iran can maintain stability and achieve development.”
