Talking to the Wall Street Journal about the July 2015 deal between Iran and the world powers that was led to lifting of anti-Iran sanctions in January, 2016, Mogherini said 'It is an international agreement in the framework of the United Nations,…There is no way the agreement can be reopened bilaterally.'
Mogherini also warned that one of the first fallouts of a US decision to walk away from the Iran deal would be a clash with Russian President Vladimir Putin, who helped secure it.
'Yes, I think it is in the interest of the United States that the deal continues to be implemented,' Mogherini responded when asked by the international newspaper if the agreement can survive.
Mogherini said she believed such common interests, including counterterrorism, crisis prevention in key regions and fighting migrant-smuggling gangs between EU and US, could lead the new US administration to work with Europe in implementing the Iranian nuclear deal.
European diplomats have said that in recent discussions, Trump aides have signaled he is unlikely to scrap the nuclear deal, known as the Comprehensive Plan Of Action.
The EU officials have also warned that if the US walks away from the agreement, the bloc won't feel obliged to reimpose sanctions on Tehran.
