"To underscore our commitment to a diplomatic solution and to enhance prospects for success, as soon as Iran fully and verifiably suspends its enrichment and reprocessing activities, the United States will come to the table," Secretary of State Condoleezza Rice said at the State Department.
Asked at a news conference whether the United States would be willing to re-establish diplomatic relations with Iran, Rice ruled out a "grand bargain" and cited major disagreements between the two countries on many issues. However, Rice said a negotiated solution to the nuclear dispute could "begin to change the relationship."
"We urge Iran to make this choice for peace, to abandon its ambition for nuclear weapons," she said. At the same time, Rice acknowledged Iran has a right to civil nuclear energy.
"The Rice announcement certainly throws the ball in Tehran's court," said CBS News foreign affairs analyst Pamela Falk from the U.N., "but it forces Russia and China to agree to eventual sanctions if Iran does not comply, and it is still unclear if they have agreed to that condition."
"It also requires a suspension of uranium enrichment by Iran," added Falk, "and one can expect to hear a negative response from Tehran."
The Swiss ambassador to the United States was called to the State Department earlier Wednesday to receive a copy of Rice's remarks for transmission to Iran, U.S. officials said. The United States has had no diplomatic ties with Iran and few contacts at all with its government since Islamic radicals took over the U.S. Embassy in 1979 and held diplomats there for more than a year.
In Brussels, European Union foreign policy chief Javier Solana welcomed Rice's remarks. "Direct U.S. participation would be the strongest and most positive signal of our common wish to reach an agreement with Iran," Solana added.
British Foreign Secretary Margaret Beckett said European nations will offer Tehran "a serious and substantial" package to cooperate. "We are all striving to reach a diplomatic solution. The European side's goal is to present a serious and substantial offer of cooperation, which demonstrates to Iran the benefits that would flow from compliance," Beckett said, "rather than the further isolation which would result from their failure to do so."
The Bush administration has been deeply suspicious of Iran's intentions and the prime mover for tough United Nations action against the clerical regime. Until now, the United States has refused repeated calls from European nations, other diplomats and former secretaries of state to join the European talks.
For its part, Iran has for months refused to do what the U.S. is now demanding as a first step to talks — suspend its enrichment of uranium, which Tehran claims is for peaceful purposes. Iran did voluntarily suspend those activities while talks were active with the Europeans last year, but resumed and stepped up those activities this spring.
Suspending uranium enrichment and related activities in order to talk with the United States would not preclude Iran from later insisting that it be allowed to continue those activities. At that point, the United States and its allies would be expected to move for tough U.N. Security Council action, possibly including economic or other sanctions.
Rice will meet with foreign ministers from the other permanent Security Council members on Thursday in Vienna to finalize a package of incentives and threats to be presented to Tehran.
"We hope that in the coming days the Iranian government will thoroughly consider this proposal," Rice said.
European diplomats told The Associated Press that the package and the U.S. announcement of a willingness to talk were conditioned on pledges from Russia and China to eventually support tough actions such as sanctions if Iran continued to defy a U.N. call to stop its disputed activities.
White House spokesman Tony Snow said the United States will not enter one-on-one talks with Iran. The European talks included Britain, France and Germany.
"There are going to be some changes, but the overall position, which is that Iran needs to take the first step, it needs to suspend enrichment and reprocessing activities, that's still there," Snow said. "That's still the foundation stone for U.S. diplomatic policy on this."
Rice also detailed other U.S. complaints with Iran's behavior, including what the U.S. says is Iran's support for terrorism in Lebanon and Palestinian territories. "Nobody is confused about the nature of this regime," she said.
