In a letter to United Nations Secretary General Antonio Guterres on Saturday, Zarif explained about several matters related to the unlawful withdrawal of the US from the nuclear deal, officially known as the Joint Comprehensive Plan of Action (JCPOA), and the unlawful imposition of its unilateral sanctions against the Iranian people and government in blatant violation of its obligations under international law.
He also brought to the UN chief's attention matters related to "multiple, continuous and grave" cases of violation of the United Nations Charter, in particular Article 25 thereof, that are jeopardizing the UN credibility and integrity, and threatening international peace and security.
He added that US President Donald Trump on May 8, 2018 officially announced his country's unilateral withdrawal from the JCPOA "in material breach of Security Council Resolution 2231 (2015) to which the JCPOA is annexed."
"The unlawful US act of unwarranted withdrawal from the JCPOA and the re-imposition of its sanctions entail the US responsibility under the UN Charter and international law," the Iranian foreign minister said.
He emphasized that the US has violated Resolution 2231 which was in fact submitted by the United States itself and was adopted unanimously by the Security Council on July 20, 2015 to endorse the JCPOA.
"The United Nations needs to address swiftly the US responsibility and hold it accountable for the consequences of its wrongful act that flies in the face of the United Nations Charter and international law. Impunity of the United States in this case and other instances would greatly impair the credibility of the United Nations," Zarif pointed out.
