Press TV - The European Union's foreign affairs chief Federica Mogherini�has stressed that the historic nuclear deal with Iran is an international agreement endorsed by the United Nations.

"The nuclear deal doesn't belong to one country, it belongs to the international community,"�Mogherini said during a joint press conference with Russian Foreign Minister Sergei Lavrov on Tuesday.

"We have the responsibility to make sure that this continues to be implemented," she added.

Iran and the five permanent members of the United Nations Security Council - the United States, Britain, France, China and Russia - plus Germany signed the Joint Comprehensive Plan of Action (JCPOA) on July 14, 2015 and started implementing it on January 16, 2016.

The UN Security Council later unanimously endorsed a resolution that effectively turned the JCPOA into international law.

During his presidential campaign, US President Donald Trump described the nuclear accord with Iran as a �disaster� and vowed to unilaterally scrap it. While he has not carried out that threat, his administration is conducting a �review� to see whether the provision of sanctions relief to Iran -�a US commitment under the deal -�is in America�s �national interest.�

Earlier in the day, Russian Deputy Foreign Minister Sergey Ryabkov hailed Iran�s full commitment to its obligations under the JCPOA and said Moscow pursues a firm stance on the deal and believes that there is no replacement for�it.

He also decried the US unilateral approach to international issues, particularly the JCPOA.
