U.S. President Donald Trump said the next phase of negotiations with Iran is expected to be easier than the first round of talks that led to the recently announced Memorandum of Understanding, while attempting to reassure concerns about possible American funding to Tehran.

Speaking at his meeting with Qatar's emir on the margins of the G7 summit in France, Trump argued that the next talks would be less difficult than those preceding.

"We are going through a second stage, which I believe will actually be easier," he said.

According to American officials, the next phase of the negotiations will focus on technical issues relating to Iran's nuclear programme, as well as financial relief for Tehran. The table also contains details of the reopening of the Straits of Hormuz, a crucial maritime route for global energy trade.

The American president also insisted that the United States would not allocate their own funds to Iran, attempting to limit the reactions expressed by some of its political allies.

"We are not going to invest money in Iran," Trump stressed.

These statements come after discussions on the creation of a $300 billion reconstruction fund, which could contribute to the reconstruction of the Iranian economy if there is a definitive agreement on the nuclear programme and the commitments provided for in the Understanding Memorandum are met.

Officials participating in the talks have clarified that this fund will not be funded by the United States, but by Gulf States, which are expected to play an important role in the economic support for Iran's post-war recovery, provided the agreement goes ahead.
