A further round of sanctions by Donald Trump against Iran went into effect Tuesday, but the president is failing to get buy-in from allies and rivals, who pledge to keep dealing with Iran.

Chinese automakers are flooding into Iran to replace French car companies there. China has pledged to pay no attention to the Trump threats.

VOAnews writes:

State-owned and private auto companies currently assembling or importing Chinese models have a nearly 10 percent share of the Iranian market, which analysts say will likely expand rapidly in the wake of the French departure. Chinese enterprises currently command a 50 percent share of auto parts imported into Iran.

The European Union has signaled that it may impose substantial fines on European firms that pull out of Iran deals over fear of Trump’s unilateral U.S. Treasury Department sanctions.

It is likely that smaller European companies that trade with Iran but have no relationship with the U.S. will continue their relationship with the Islamic republic, using euros and non-U.S. banks. But large firms, such as French oil giant Total S.A. and Renault, have signaled that they will get out of Iran to avoid American fines. It is hard to imagine them taking this risk or that EU fines could offset the threat of American ones. The U.S. has fined European banks billions for dealing with Iran in the years before the 2015 U.N. Security Council Iran deal.

The European announcement is likely intended to reassure Iran of continued commitment to the Joint Comprehensive Plan of Action by the European Union member states, and to forestall an Iranian return to large-scale nuclear enrichment (which Iran maintains was for peaceful purposes).

Russia may be happy with Trump in general, but his assault on the Iran deal is driving the Kremlin up the wall. Russia needs Iranian help in Syria, and its businesses want to invest in Iran to take advantage of the good feeling produced by the alliance. Russia is planning to invest $50 billion in Iranian oil and natural gas, and doesn’t welcome Trump interference in this plan.

The Russian Foreign Ministry issued a statement that said, “We are deeply disappointed with US efforts to reinstate national sanctions against Iran.”

It complained that “[t]his is a graphic example of Washington’s continued violation of UN Security Council Resolution 2231 and trampling upon the norms of international law.”

Moscow denounced any unilateral sanctions that went behind the back of the U.N. Security Council, especially if they involved third-party sanctions (i.e., Russia is upset about the prospect of the U.S. imposing sanctions on Russian firms investing in Iran, not just on Iran itself).

Russia observed, “The JCPOA has completely proved its worth and efficiency. The [International Atomic Energy Agency] regularly confirms that Iran unfailingly honours its obligations. The Plan’s verification, control and monitoring measures are being carried out in full. This itself reliably attests to the peaceful nature of the Iranian nuclear programme.”

Moscow called on the international community to prevent the U.S. from subverting the achievements of multilateral diplomacy, and expressed confidence that the parties to the treaty can keep it in place.”
