Fact Sheet: First Step Understandings Regarding the Islamic Republic of Iran’s Nuclear Program

The P5+1 (the United States, United Kingdom, Germany, France, Russia, and China,

facilitated by the European Union) has been engaged in serious and substantive negotiations

with Iran with the goal of reaching a verifiable diplomatic resolution that would prevent Iran

from obtaining a nuclear weapon.

President Obama has been clear that achieving a peaceful resolution that prevents Iran from

obtaining a nuclear weapon is in America’s nation al security interest. Today, the P5+1 and

Iran reached a set of initial understandings that halts the progress of Iran's nuclear program

and rolls it back in key respects. These are the first meaning ful limits that Iran has accepted

on its nuclear program in close to a decade. The initial, six month step includes sig nificant

limits on Iran's nuclear program and begins to address our most urgent concerns including

Iran’s enrichment capabilities; its existing stockpiles of enriched uranium; the number and

capabilities of its centrifuges; and its ability to produce weapons-grade plutonium using the

Arak reactor. The concessio ns Iran has committe d to make as part of this fi rst step will also

provide us with increase d transparency and intrusive m onitoring of i ts nuclear program. In

the past, the concern has been expressed that Iran will use negotiations to buy time to

advance their program. Taken together, thes e first step measures will help prevent Iran from

using the cover of negotiations to continue advancing its nuclear program as we seek to

negotiate a long-term, comprehensive solution that addresses all of the international

community's concerns.

In return, as part of this initial step, the P5+1 will provide limited, temporary, targeted, and

reversible relief to Iran. This relief is structured so that the overw helming majority of the

sanctions regime, including the key oil, banking, a nd financial sanctions architecture, remains

in place. The P5+1 wil l continue to enforce these sanctions vigor ously. If Iran fails to meet its

commitments, we will revoke the limited relief a nd impose additional sanctions on Iran.

The P5+1 and Iran also discussed the general parameters of a comprehensive solution that

would constrain Iran's nuclear program over the long term, provide verifiable assurances to

the international community that Iran’s nuclear ac tivities will be exclusively peaceful, and

ensure that any attempt by Iran to pursue a nuclear weapon would be promptly detected.

The set of understandings also includes an acknowledgment by Iran that it must address all
