U.S. Secretary of State Hillary Clinton said that next month the Senate Foreign Relations Committee will bring the new START treaty, signed by Barack Obama and Dmitry Medvedev in Prague this year, one step closer to ratification.

“Opposing ratification means opposing the inspections that provide us a vital window into Russia’s arsenal,” Clinton told a briefing on Wednesday.

Last week the Senate Foreign Relations Committee delayed a vote on the treaty until September.

The U.S. Senate will consider ratification after the document is approved by the Foreign Relations Committee.

The treaty signed this April calls for reducing nuclear warheads to 1,550 and delivery vehicles to 700 - ballistic missiles and heavy bombers.

The document will come into force after it is ratified by the U.S. and Russian Parliaments.
