US President Joe Biden and French President Emmanuel Macron discussed strengthening European defences in a telephone call today, the White House said as Washington seeks to mend ties after a bitter row over submarine contracts.

The two leaders "discussed efforts to enable a stronger and more capable European defense while ensuring complementarity with NATO," the statement said.

Mr Biden will meet Mr Macron in Rome later this month, and the statement said he looked forward to the chance to "take stock of the many areas of US-France cooperation, and reinforce our shared interests."

The two last spoke on 22 September for their first conversation since the furious spat over selling submarines to Australia severely strained relations.

Specifically, Australia agreed to acquire US nuclear sub technology and in doing so scrap a huge, already existing deal with France to buy conventional submarines. The new accord infuriated the French.

Mr Macron recalled France's ambassador to Washington and Foreign Minister Jean-Yves Le Drian compared Mr Biden's unilateral methods to ex-president Donald Trump's but "without the tweets."

Although Mr Biden did not apologise for secretly negotiating to sell nuclear submarines to Australia, he did acknowledge that the issue "would have benefited from open consultations among allies," according to a statement afterward.

US officials have since sought to patch up ties, with US Secretary of State Antony Blinken visiting Paris earlier this month and holding a one-to-one meeting with Mr Macron.

In their September call, Mr Macron secured what he saw as a significant commitment from Biden to respect French-led efforts to boost European defense and autonomy.

US Vice President Kamala Harris will also hold talks with Mr Macron in Paris next month, the White House announced.
