The European Union (EU) and the United Nations (UN) have restated support for the Iranian nuclear accord on the first anniversary of the historic deal’s implementation.

The nuclear deal, which is also known as the Joint Comprehensive Plan of Action (JCPOA), was signed by Iran and six world powers including the US, the UK, France, Russia, China, and Germany in July 2015.

It was implemented on January 16, 2016 and ended nuclear-related sanctions against Iran in return for some limits on Tehran’s nuclear program.

Federica Mogherini once again reaffirmed EU’s support for the deal in the face of potential threats from the upcoming US administration.

“The full and effective implementation throughout the entire lifetime of the JCPOA remains essential,” said Mogherini in a statement.

“The EU has clearly affirmed its resolute commitment to this objective.”

She also said the bloc “will continue to work hand in hand with all those willing to contribute to its full implementation and in achieving the objectives which brought us together.”

After the election of Donald Trump as the president of the United States, there has been concerns over his words about the implementation of the nuclear deal.

He has described the deal as a very bad one and previously threatened to “tear up” the accord.
