Welcome
The Iranian nuclear programme
After a protracted conflict surrounding the Iranian nuclear programme due to justified doubts about its exclusively civilian nature, Germany, France, the UK, the US, Russia, China and Iran signed the so-called JCPOA on 14 July 2015 in an attempt to resolve this crisis at the negotiating table.
The United Nations Security Council approved the Joint Comprehensive Plan of Action (JCPOA) with Resolution 2231 (2015), and it took effect on 18 October 2015. As coordinator, the High Representative of the European Union plays a key role in the implementation of the JCPOA, which initially met with success.
Until mid-2019, the International Atomic Energy Agency (IAEA) repeatedly confirmed in its quarterly reports that Iran was adhering to the JCPOA undertakings. Iran also benefited from the agreement. Sanctions were eased as agreed and the country’s economy and foreign trade with Germany grew.
The JCPOA in crisis
On 8 May 2018, US President Donald Trump announced the United States’ withdrawal from the JCPOA. The US re-imposed the sanctions against Iran that it had previously suspended and gradually enforced further restrictive measures. Many of these measures are secondary sanctions, which had an extra-territorial effect on Iran’s trading partners in third countries.
Iran has been gradually abandoning its nuclear-related commitments under the JCPOA since 1 July 2019 and further stepped up its systematic violations of the JCPOA on the basis of a “strategic nuclear law” passed in December 2020. Iran increased its production of low-enriched uranium, began enriching uranium up to 60 percent, abandoned the agreed limits for research and development on advanced centrifuges, recommenced uranium enrichment at the underground plant in Fordow, reduced transparency with regard to its nuclear programme by restricting access for inspectors and started experiments to extract uranium metals without plausible civilian justification.
The Vienna talks on the restoration of the JCPOA
The US administration under President Biden announced its determination to return to the nuclear agreement and to repeal the nuclear-related secondary sanctions imposed or reinstated by the previous administration, provided Iran also adhered once again to its obligations. Negotiations between the JCPOA participants and the US were held in Vienna from April to June 2021 and from November 2021 to March 2022, during which an agreement on these issues was outlined. However, Iran ultimately rejected the compromise packages submitted in March and August 2022 by the EEAS as coordinator, thus preventing the restoration of the JCPOA. In view of Iran’s significant and ongoing breaches of the JCPOA, the E3 has retained the nuclear-related sanctions at EU level and under UK law, although under the JCPOA these were due to be repealed on Transition Day (18 October 2023). This step does not mean the end of the JCPOA, but can be reversed if Iran lives up to its obligations under the agreement.
Since the failure to restore the JCPOA in 2022, no further negotiations of this kind have taken place. The Iranian nuclear programme has now reached a particularly dangerous level. The German Government continues to seek a diplomatic solution to this crisis.
