"In our view, the treaty due to replace the START treaty should also limit the means of the delivery of nuclear warheads, and not only the number of warheads. I mean by this intercontinental ballistic missiles, submarine ballistic missiles and heavy bombers carrying nuclear loads," Dmitry Medvedev said at Helsinki State University.
He also said the very "possibility of placing strategic nuclear armaments beyond national borders" should be ruled out, and spoke against deploying weapons in space.
The START-1 treaty, signed in 1991, obliged Washington and Moscow to cut nuclear warheads to 6,000 and their delivery vehicles to 1,600 each. The treaty expires on December 5 this year.
In 2002, an additional agreement on strategic offensive reductions was concluded in Moscow. The agreement, known as the Moscow Treaty, envisioned cuts to 1,700-2,200 warheads by December 2012. However, that treaty is largely considered by analysts to be less effective than the START treaty.
Medvedev also said that during his recent London meeting with U.S. President Barack Obama it had been agreed that negotiators would immediately start talks on a new strategic arms reduction treaty.
