President Donald Trump denied Wednesday that the U.S.-Iran peace deal included a $300 billion fund, claiming that Washington will not be investing 10 cents.

Earlier reports suggested that the U.S.-Iran framework proposed a private fund designed to trigger investment into Iran.

According to Reuters, the fund would be designed to give both sides an economic incentive to conclude a final deal to end the war.

The U.S. president added that the memorandum ⁠of understanding on ⁠Iran was not final, and that ​he could ​resume a bombing ⁠campaign if he did not like it.

"It's a memorandum of understanding. And if I don't like it, we'll go back to shooting at them, dropping bombs on their head," Trump said at a G-7 summit in France.

"If I don't ​like it, if they don't behave, we'll go right back to dropping bombs right smack in ​the ⁠middle of their head, OK?"

Leaders of the G-7 countries demanded a cease-fire in Lebanon Wednesday and said they will diversify energy supply routes to reduce dependence on the Strait of Hormuz in response to the war in Iran, as they welcomed the interim deal to end it.

The leaders met for a summit in the French town of Evian-les-Bains, an hour's drive along the shore of Lake Geneva from where the memorandum is due to be signed at a ceremony across the Swiss border Friday.

The U.S.-Iran agreement is expected to launch negotiations towards a final settlement to end the war, which has killed more than 7,000 people, mostly in Iran and Lebanon.

"We underline the need for the negotiation ... to address the threats posed by Iran in the region and beyond and ensure that they never obtain a nuclear weapon," the leaders said in a statement.

The summit gave Trump a chance to present his deal with Iran to ⁠allies ⁠Britain, Canada, France, Germany, Italy and Japan.

They share Washington's concerns about Iran's nuclear program and other issues, but never endorsed his decision to go to war and worry Tehran has gained leverage by withstanding the superpower onslaught and asserting control over the strait.

The leaders said they were ready to contribute to the implementation of the accord, with a coalition led by Britain and France set to help secure shipping once the Strait of Hormuz reopens.

The memorandum of understanding signed by Washington and Tehran this week, though yet to be made public, extends a cease-fire announced in April by another 60 days to allow them to negotiate a permanent truce.

Trump appears to have achieved little of what he said he wanted at the outset of the war. Iran's theocratic government remains in place, its ⁠stockpile of highly enriched uranium has not been surrendered, its ballistic missile capabilities have not been destroyed and it has not ended its support for anti-Israel militias like Hezbollah in Lebanon.

Trump says the agreement states that Iran will not have a nuclear weapon – a restatement of Iran's official position since the 1970s. U.S. officials say further ​discussions will lead to the removal or destruction of its enriched uranium stockpile.

But ending the war on such terms could still expose ​Trump to criticism, including from hawks within his own Republican party, ahead of midterm elections in November.

Lebanon truce?

One of the biggest questions still hanging over the truce is the fate of Lebanon, which Israel invaded in March to root out Hezbollah after ⁠the militant group ‌fired across ‌the border in solidarity with Tehran following U.S.-Israeli strikes on Iran.

Israeli forces still occupy a swathe ⁠of southern Lebanon, where more than a million people have been driven from their homes, ‌while Hezbollah remains undefeated.

Iran says the cease-fire must also end hostilities in Lebanon and that a permanent deal must lead to an Israeli withdrawal.

Israel, which was excluded ​from the U.S.-Iran peace negotiations, says it will not ⁠withdraw and reserves the right to use military force.

That has opened up a rift between Israel ⁠and the United States, with Trump publicly berating his wartime ally, Israeli Prime Minister Benjamin Netanyahu.

In their statement, the G-7 leaders called for ⁠an "immediate robust cease-fire" in Lebanon and ​the disarmament of Hezbollah.

Oil prices fell again on Wednesday on prospects for the reopening of the Strait of Hormuz, with Brent crude futures below $80, at their lowest level since the opening salvos of the U.S.-Iran conflict.
