EU 'extremely worried' about fate of nuclear treaty

NATO Secretary General Jens Stoltenberg greets the European Union's top diplomat Federica Mogherini in Brussels amid warnings the security of Europe could be at risk over threats to a major US-Russia nuclear missile treaty

The EU's top diplomat Federica Mogherini said Tuesday she was "extremely worried" about the fate of a major US-Russia nuclear missile control treaty, warning the security of Europe could be at risk.

Last month, Washington announced it was pulling out of the Intermediate-Range Nuclear Forces Treaty (INF) over Russia's deployment of a missile system that Western powers say breaches the 1987 accord.

The Kremlin has warned of a new arms race, and as she convened a meeting of EU defence ministers Mogherini expressed concern, calling for talks to save the agreement.

"If we go towards the dismantling of this agreement, Europe's security is to be put at risk and we do not want to see European territory go back to being a battlefield for other powers as it has been for so long in the past," she told reporters.

"We don't want to go back to those kind of tensions, to that kind of situation and we still hope there is a space for saving the agreement and implementing it," she said.

While US President Donald Trump's administration has signalled it will withdraw from the treaty, it has not taken steps to put the decision into practice.

The INF treaty, signed by then US president Ronald Reagan and Soviet leader Mikhail Gorbachev, ended a nuclear build-up in Europe triggered by Moscow's deployment of SS-20 missiles targeting Western European capitals.

The US and NATO say Russia's 9M729 missile system, also known by the designation SSC-8, breaches the treaty, which prohibits ground-launched missiles with a range of between 500 and 5,500 kilometres.

Washington says repeated attempts to persuade Russia to come back into compliance since 2013 have been met with silence or obfuscation.

NATO Secretary General Jens Stoltenberg said Europe should demand "full and transparent compliance" with the treaty from Russia.

"Russia has developed, tested and also fielded new missiles, SSC-8, for years. These missiles are mobile, hard to detect, nuclear capable and they are putting the INF Treaty in jeopardy," Stoltenberg said as he arrived to join the EU ministers for talks.

"The US is in full compliance with the INF Treaty, there are no new US missiles in Europe, but there are new Russian missiles in Europe."

Trump and his Russian counterpart Vladimir Putin discussed the INF treaty during a brief conversation at World War I centenary events in Paris last week.
