Recovering from last week’s multi-month lows on Monday, prices declined again as indirect talks on reviving Iran’s nuclear accord between Tehran and Washington mediated by the European Union concluded in the Austrian capital Monday, with a final draft of the agreement on the table.
Iran confirmed relative progress on remaining issues in this round of talks that began Thursday after a five-month hiatus, with discussions still up for debate.
A senior official in Iran's Foreign Ministry was quoted Monday as saying by the state news agency IRNA that the Iranian negotiating team, led by Deputy Foreign Minister Ali Bagheri Kani, had informed other parties of its positions on the new draft text proposed by the EU.
He said Iran conveyed its 'initial response and reservations' to proposals in the new text on remaining issues made by EU Foreign Policy Chief Josep Borrell.
The remarks came after the EU said Monday it had put forward a 'final' text to salvage the 2015 nuclear accord after four days of intense talks in Vienna between the parties to the deal, known formally as the Joint Comprehensive Plan of Action (JCPOA).
The deal, if approved, would allow Iran to start oil exports, which some experts expect to be around 1.5 million barrels per day over six months.
Last week, prices dropped to the lowest levels of the past six months over worries that weak economic data released in the US and Europe would negatively impact the oil demand outlook.
However, concerns over a global economic recession eased slightly over positive data from China, the world's largest crude oil importer.
The country imported 8.79 million barrels of oil per day in July, up from June's import levels but 9.5% less than a year earlier, according to China's customs data.
