France and the United States clashed over the future of the West today as Emmanuel Macron blasted the Americans for turning their backs on Europe.

The French President dismissed claims by US Secretary of State Mike Pompeo that the transatlantic alliance was still strong.

He told the Munich Security Conference: 'There is a weakening of the West.

'There's an American policy that started several years ago and not just under this administration that includes a certain kind of withdrawal, of a rethink of its relationship with Europe.'

Pompeo earlier rejected European pessimism about Washington's retreat from the global stage, saying the death of the transatlantic bond had been 'grossly over-exaggerated'.

He said: 'The West is winning and we're winning together.'

The annual gathering of world leaders, generals and diplomats to discuss security challenges has been dominated by fears of diminishing Western influence in the face of a more assertive China and Russia.

French President Emmanuel Macron says the West is 'weakening'

In his opening speech yesterday, German President Frank-Walter Steinmeier suggested that the United States rejected 'even the idea of an international community' and was acting 'at the expense of neighbours and partners'.

'Those statements don't reflect reality,' Pompeo retorted.

'I'm happy to report that the death of the transatlantic alliance is grossly over-exaggerated,' he said, paraphrasing a famous Mark Twain quote.

He said Washington was playing a key role in keeping Europe safe by reinforcing NATO's eastern flank on the border with Russia, as well as leading a multinational effort to defeat the Islamic State jihadist group.

Pompeo added: 'Is this an America that 'rejects the international community'?

'The free West has a brighter future than illiberal alternatives.'

Pompeo urged allies to have 'confidence' in the transatlantic bond.

He stressed the need to work together against threats posed by Russia's territorial ambitions, China's military buildup in the South China Sea and Iran's 'campaigns of terror' through proxy conflicts in the Middle East.

Macron said on Saturday that Europe's policy of defiance towards Russia in recent years had failed and, as nobody wanted to confront Moscow directly, the only option was to have a closer dialogue to resolve differences.

'I hear the defiance of all our partners, I'm not mad, but I know that being defiant and weak ... it is not a policy, it's a completely inefficient system,' he said, adding that he saw none of his allies willing to confront Russia.

'There is a second choice which is to be demanding and restart a strategic dialogue because today we talk less and less, conflicts multiply and we aren't able to resolve them.'
