The concept of the missile shield is not directed against Russia, U.S. Secretary of State Condoleezza Rice said after the meeting of G8 foreign ministers, and Russia could easily penetrate the planned system in any event.
In response, Sergei Lavrov called the reassurances "laughable."
"So far, we have just been told, 'Don't worry, this is not directed against you.' Yet our analysis shows that such responses are laughable to hear," Lavrov said.
"There are material facts on the ground: this global missile defense is being - by accident or deliberately - deployed around Russia. I don't think this is something Russia should take lightly, and I hope our U.S. partners respect our analysis, laid out in the finest detail and in a very professional manner," he said.
He said he expected a response from the U.S., which would be "as professional and as specific."
"The chief and the only motive for making this decision [to propose a missile shield in Central Europe] was a nuclear threat from North Korea and Iran. The analysis shows that the North Korean nuclear threat should be removed in a united effort during the six-sided negotiations. As to Iran, [this analysis] clearly demonstrates that missiles whose range would justify a missile defense system against such an Iranian threat are non-existent now and will not be there in the foreseeable decades," Lavrov said.
The U.S. wants to deploy a missile defense radar in the Czech Republic and 10 interceptor missiles in Poland on a bilateral basis.
Since Washington aired the exact plans earlier this year, Russia has opposed the deployment, citing its own national security concerns. Some of Russia's top generals hinted that the bases, if opened, could be targeted by Russian missiles.
U.S. NATO allies in Europe, notably Germany, have also questioned whether it was appropriate to talk to EU and NATO members bilaterally, instead of opening a broad transatlantic debate.
The U.S. Congress earlier this month reduced funding for the bases but left the Bush administration the option of re-applying for the funds at a later juncture.
