Moscow, Oct 14: The Russian Foreign Ministry has expressed regret over the decision of US President Donald Trump to decertify Iran's compliance with a nuclear deal, arguing that Tehran strictly abides by the landmark agreement. Trump blamed Iran for committing "multiple violations" of the nuclear pact, formally known as Joint Comprehensive Plan of Action (JCPOA), and "not living up to the spirit of the deal". "The Russian Foreign Ministry emphasizes the inadmissibility of using aggressive and threatening rhetoric in international relations," it said in a statement on Friday, Xinhua news agency reported. Attempts to use such methods to solve foreign policy problems affecting the fundamental security interests of other countries are doomed to failure, it said. "Iran strictly adheres to its obligations, which is regularly confirmed by the International Atomic Energy Agency," the statement read. The JCPOA, which is multilateral and supported by United Nations Security Council Resolution 2231, has already contributed to the strengthening of international peace and security and the creation of a more predictable atmosphere in the Middle East, according to the Russian ministry. Russia remains committed to the JCPOA and will continue to fulfil its obligations under it, said the ministry, calling on all other participants to do the same.
