Foreign ministers from six key nations will likely meet late next week to take a final decision on a package of incentives to reward Iran if it suspends uranium enrichment and penalties if it doesn't, a senior UN diplomat said.
The ministerial meeting will follow up on Wednesday's meeting in London of political directors from the five veto-wielding nations on the UN Security Council and Germany who have been leading international efforts to rein in Iran's nuclear program.
US Undersecretary of State Nicholas Burns said Thursday that Washington was "very pleased" at the "very productive, very constructive" talks. British Foreign Office representative John Sawer also spoke of "good progress" on eliminating differences about how jointly to pressure Iran on enrichment.
"The positive aspect," said Britain's UN Ambassador Emyr Jones Parry, "is that they're moving closer to an agreement on the content of the package."
