Trump’s comments came after he was asked whether he had called on other G7 members, including Britain, Germany and Japan, to send their armed forces in connection with the Strait of Hormuz.

The strait, a critical global shipping route, has been effectively closed since shortly after the United States and Israel launched air strikes on Iran at the end of February.

But just ahead of the G7 summit, the US and Iran reached a preliminary peace deal that will include extending a ceasefire for another 60 days and Tehran reopening the waterway.

The G7 is a bloc consisting of Canada, France, Germany, Italy, Japan, the United Kingdom and the United States. The EU is also represented within the G7.
