Iranian Foreign Minister Javad Zarif said the US unilateral withdrawal from the Joint Comprehensive Plan of Action (JCPOA) is unlawful and a material breach of United Nations Security Council Resolution 2231 (2015) to which the deal is annexed.
Zarif came up with the remark in a letter to the Secretary General of the UN, António Guterres, regarding the US withdrawal from the deal and re imposition of sanctions on Iran.
The Embassy of the Islamic Republic of Iran in Dhaka on Wednesday handed over the letter to the Foreign Ministry of Bangladesh.
Zarif said the unilateral decisions of the US constitute a complete disregard for international law and the United Nations Charter.
The decisions also undermine the principle of peaceful settlement of disputes, endanger multilateralism and its institutions, he continued.
The US actions indicate a regress to the failed and disastrous era of unilateralism, and encourage intransigence and illegality, he maintained.
Zarif said his country has scrupulously fulfilled its undertakings under the JCPOA, but the US has consistently failed - since "implementation day" to abide by its commitments under the deal.
The Iranian foreign minister recalled that he has brought the most significant cases of U.S. non-performance to the attention of the Joint Commission inter alia through 12 official letters.
He has sent the letters to the High Representative of the European Union for Foreign Affairs and Security Policy, in her capacity as Coordinator of the JCPOA Joint Commission.
Zarif mentioned that the unlawful U.S.withdrawal renders it responsible for the most blatant material breach of its obligations under the agreement.
The U.S. has also flagrantly violated UNSC resolution 2231, which was sponsored inter alia by the US itself and adopted unanimously by the Council, he noted.
The US must, therefore, be held accountable for the consequences of its reckless and wrongful act that flies in the face of the United Nations Charter and international law, he said.
Zarif said the official re-imposition of unlawful sanctions by the US have caused irreparable harm to Iran and its international business relations.
The US should be held responsible for these damages, and the Iranian nation must be compensated, he claimed.
The Iranian foreign minister said if the deal is to survive; the remaining JCPOA Participants and the international community need to fully ensure that Iran is compensated unconditionally through appropriate national, regional and global measures.
“If our people's rights and benefits are not fully compensated, Iran has right to take appropriate action in response to persistent, numerous unlawful acts by the US,” he added.
Zarif also urged the UN to keep the US accountable for its unilateral and irresponsible conduct which will detrimentally affect the rule of law, multilateralism, and foundations of diplomacy.
