In 2018, President Donald Trump decided to withdraw from the JCPOA. This move was confirmed by the President’s
National Security Memorandum of May 8, 2018, as well as by Executive Order 13846 of August 6, 2018, which renewed unilateral US sanctions against Iran. Yes, the United States is a permanent member of the UN Security Council. But Clause 11 of UN Resolution 2231 says that the issue of non-compliance with the JCPOA can be raised by its participant. Since the US withdrew from the “deal”, it cannot raise the issue of compliance with the JCPOA. This means that the US notification of August 20, as well as the subsequent announcement of the renewal of UN sanctions, has no effect. Technically, a notice of non-compliance could have been sent by another party to the deal, and then the US could veto the resolution. But this did not happen, since none of the permanent members of the UN Security Council supported Washington’s unilateral actions.
The current situation gives rise to uncertainty about the further development of the situation, including the supply of weapons to Iran. In theory, any state can sell such supplies. In practice, there will be few people or companies willing to sell weapons to Iran due to fears of secondary US sanctions. An exception can be made by two countries: China and Russia.
China may raise the issue of military deals with Iran, given the growing pressure from Washington on Beijing. The very fact of raising such a question, which is quite legitimate from the point of view of international law, will be an argument in the hands of China to contain the pressure of the United States. However, China will be more prudent because the Americans have already used sanctions against Chinese companies, arguing along the Iranian line. Its attacks against ZTE and Huawei at one time began precisely for the alleged violation of US sanctions against Iran. The same applies to the sanctions against the Chinese sea carrier COSCO Shipping Tanker and a number of other companies.
Russia can come up with a more active policy. Relations between Moscow and Washington have been rock bottom for a long time. In the doctrinal documents of the United States, Russia, China and Iran are placed on the same level: as authoritarian and aggressive countries. There are very large-scale sanctions against Russia. Rosoboronexport and a number of defence industry enterprises have already been blocked by the US Treasury under the Syrian or Ukrainian packages of sanctions. That is, Executive Order 13949 is simply not a threat to them. Of course, the United States can respond to arms supplies to Iran with separate countermeasures. For example, to make more active use of the CAATSA provisions on secondary sanctions against buyers of Russian arms. Sanctions can be imposed against a wide range of counterparties of domestic arms manufacturers both in Russia and abroad. But the appearance in the hands of Iran of C-300 weapons systems, Su-30 fighters or other systems is also a serious argument. In an atmosphere of confrontation, its expediency may outweigh the considerations of those who are in favour of detente, minimising damage and preserving the remnants of the partnership. The worst scenario for the United States is the consolidated actions of Moscow and Beijing on military-technical cooperation with Iran on the basis of Resolution 2231.
Among other things, Russia and China may raise the issue of unilateral sanctions against the United States for violating international law. On September 19, 2020, a
separate legal mechanism for imposing sanctions appeared in China . It is focused on protecting the national interests and sovereignty of the PRC and was created, apparently, in response to the growing number of US sanctions against China. However, it is possible that it can be used on other issues, including international agreements in which the PRC participates.
In Russia, the Federal Law of 30.12.2006 No. 281-FZ (as amended by the Federal Law of 01.05.2019 No. 83-FZ) “On Special Economic Measures and Compulsory Measures” is in force. According to article 2. of the law, special economic measures (in fact, unilateral sanctions) can be applied “in cases of a combination of circumstances that require an immediate response to an international legal act ...” In addition, the Federal Law of 04.06.2018 No. 127-FZ “On measures of influence (counteraction) to unfriendly actions of the United States of America and other foreign states” is in force. Violation of the JCPOA may be included among such actions. The decision to apply special economic measures is within the purview of the President of Russia: the existing legislation gives him such powers. Russian sanctions could serve as a political signal that Russia opposes the destruction of international agreements endorsed by the UN Security Council.
