The main focus is the Iran war and the ceasefire announced at the summit's dawn. Trump is trying to sell the deal as a breakthrough - the beginning of the end of the war - saying the Strait will open by Friday. From the European side, despite relief, there are many questions. They're skeptical about full traffic flow through the Strait before Friday. Europeans offered to help with demining but can only do that once a peace agreement is clear in their minds, which it is not.
Italy's PM Meloni says she won't be involved until there's a full agreement not just with Iran but also with Lebanon. There are also financial sanctions from the European side that the US is trying to remove. Given the ambiguity around Iran and difficulty getting an aligned position, it's unlikely there will be a clear joint communique on Iran.
