EU supports US, Iran talks but insists on nuclear deal

HELSINKI - The EU's diplomatic chief said Thursday that the bloc would support talks between the US and Tehran, but only if the current nuclear deal with Iran is preserved.

Tehran and Washington have been locked in a bitter standoff since last year when US President Donald Trump unilaterally pulled out of the 2015 deal that gave Iran relief from sanctions in return for curbs on its atomic programme.

Tensions have risen dramatically in the Gulf, where Iran has seized tankers, but EU countries are reluctant to join a US-led operation to protect commercial shipping, floating instead their own observation mission.

The idea of direct talks between Washington and Tehran as a way out of the crisis has grown this week after Trump mooted the idea and the new US defense secretary urged Iran's leaders to engage.

The EU has desperately sought to stop the deal from collapsing completely, arguing it is the best way to stop Iran developing nuclear bombs.

EU diplomatic chief Federica Mogherini gave a cautious welcome to the idea of negotiations, after Trump said Monday he was ready to meet Iran's President Hassan Rouhani within weeks.

"We are always in favour of talks, the more people talk, the more people understand each other better, on the basis of clarity and on the basis of respect," Mogherini said as she arrived for a meeting of EU foreign and defence ministers in Helsinki.

But she added "first and foremost what is existing needs to be preserved" -- specifically the 2015 deal known formally as the Joint Comprehensive Plan of Action or JCPOA.

"We will always advocate for the full respect by all sides of the UNSC resolutions and that includes the JCPOA," she said.

At the G7 summit in Biarritz, Trump showed openness to French President Emmanuel Macron's proposal of a summit with Rouhani.

US Defense Secretary Mark Esper followed up on Wednesday by urging Tehran to engage, but Iranian Foreign Minister Mohammad Javad Zarif insisted Washington must respect the deal and halt what he called "economic terrorism" against his country.

Gulf missions 

Maritime security and the Middle East are on the agenda for EU ministers meeting in Helsinki, but apart from Britain, there has been little European enthusiasm for Washington's Operation Sentinel in the Gulf.

Esper said the effort to protect shipping on crucial oil trade routes was now "up and running" with help from Britain, Australia and Bahrain.

French Defence Minister Florence Parly said that up to five countries had signed up for a potential EU observation mission.

"We must guarantee free navigation and security in the Strait of Hormuz, a vital region for the transport of hydrocarbons," she said.

"But there is no question of creating an escort force -- rather a dissuasive presence with an exchage of information."

France, which already has a warship in the region, is keen to avoid any perception that it is aligning itself to Trump's strategy of "maximum pressure" on Iran.

Iran has said that sending a "European fleet" to the Gulf would be a provocative move.

In response to the US pulling out of the deal and reimposing sanctions, Tehran has breached certain limits on its nuclear production imposed by the accord.

An EU official said the focus now was on ensuring these breaches do not become irreversible.

An Iranian delegation is expected in Paris next week and a meeting between senior Iranian and EU officials is planned soon.
