"We want these talks to be successful and we want logic to dominate the atmosphere of the talks," an unnamed Iranian official told Reuters.
But Tehran's recent declaration of a secret second nuclear enrichment facility and new missile tests this week will likely affect its strategy in the meeting with the US, Britain, France, Russia, and China – the permanent five members of the UN Security Council – plus Germany, a group known as P5+1.
"Now with the second installation revealed, it may be that [the Iranians] allow more transparency in some of the recognized [nuclear] sites, in order to divide the P5+1 and to stop the momentum against them," says Shahram Chubin, a Carnegie Endowment nonproliferation specialist based in Geneva.
