Berlin, Feb 1 (IANS) The US was keeping its doors open for direct talks with the Iranian government with regard to its controversial nuclear programme, US Vice President Joe Biden has said.
"We will stop Iran from getting a nuclear weapon," Xinhua quoted Biden as telling the Sueddeutsche Zeitung newspaper.
He said Iran's nuclear weapon must be stopped as it posed "threat to national security of the US".
However, he added that there existed "time and space" in terms of "successful diplomacy".
While a window of time for negotiations would be kept open, Biden said "it would not be unlimited, and by no means would the US stand idly by as a program for atomic bombs is developed".
A new round of talks over Iran's controversial nuclear programme is set to begin later this month after months of moratorium.
Iran Thursday informed the International Atomic Energy Agency (IAEA) of its plan to use the new centrifuges, a model called IR2m, at its uranium enriching facilities.
The West suspects Iran is making nuclear weapons. However, Iran has repeatedly said its nuclear programme has only peaceful goals.
