French President Emmanuel Macron said on Thursday France would meet its NATO-agreed goal of spending 2% of GDP on defence by 2024, saying cohesion within the North Atlantic Treaty Organization was only possible if the burden was shared "fairly".

US President Donald Trump has upbraided NATO member states for not reaching the target sooner. Aside from the United States, which spends about 3.5% of GDP on defence, only Britain, Poland, Greece and Estonia currently meet the target.

Speaking at a news conference at the NATO summit, Macron said Trump had reaffirmed the United States' commitment to the defence organisation, despite earlier expressing doubts.

France spends around 1.8% of GDP on defence.
