The leaders of the G7 countries see the framework agreement between the United States and Iran as a "historic opportunity" to prevent Tehran from acquiring nuclear weapons, according to a statement released early on Wednesday.
The deal between Washington and Tehran, which is due to be signed by both warring parties on Friday, could bring "peace and security for all in the region," the heads of the Group of Seven (G7) leading industrialized democracies said.
The leaders said they supported the implementation of the agreement and were ready to contribute to it.
On the Strait of Hormuz, the G7 reaffirmed that "the right of transit passage without restrictions or tolls is the bedrock of international trade."
The leaders said negotiations were now needed on a "robust and comprehensive diplomatic follow-on agreement" to address "the threats posed by Iran in the region and beyond" and to ensure that Iran will "never obtain a nuclear weapon."
On the conflict between Israel and the Iran-backed Hezbollah militia in Lebanon, the G7 said it supported the Lebanese leadership's efforts to achieve Hezbollah's disarmament through an "immediate robust ceasefire" and to protect Lebanon's territorial integrity "with the appropriate international security guarantees."
The summit in the French spa town of Évian brought together the leaders of the United States, Germany, France, the United Kingdom, Italy, Canada and Japan, as well as top EU representatives.
