Joe Biden's mental capacity hasn't been a consideration for Christopher Luxon in his meeting with the US President. 

He's had a chance to discuss Indo-Pacific issues with Biden at the NATO summit in Washington DC. 

The Prime Minister says Biden was sharp and "on top of his brief". 

He says Biden wanted to discuss US engagement in the Indo-Pacific region, and their interactions were positive and very engaging. 

NZ Herald Political Editor Claire Trevett told Ryan Bridge that NATO leaders are nervous to comment on Biden’s mental state as Trump is less friendly towards the organisation. 

She suspects things will get a bit messy once NATO is finished and Bien is no longer being made a fool of in front of world leaders.
