WASHINGTON, October 2 (RIA Novosti) - U.S. Secretary of State Hillary Clinton will make her first trip to Russia during a European tour on October 9-15, the U.S. State Department said in a press release on Friday.

Clinton will also travel to London, Dublin and Belfast to discuss a wide range of bilateral and global issues.

"In Moscow, the Secretary will meet with senior Russian officials to discuss progress on a successor agreement to START, cooperation on nonproliferation and counterterrorism, and next steps for the Clinton-Lavrov commission," the statement said.

U.S. President Barack Obama and Russian President Dmitry Medvedev agreed in July in Moscow on the outline of a deal to replace the 1991 Strategic Arms Reduction Treaty (START-1), which expires on December 5, including cutting their countries' nuclear arsenals to 1,500-1,675 operational warheads and delivery vehicles to 500-1,000.

Medvedev told the UN Security Council Summit on Nuclear Non-Proliferation and Nuclear Disarmament in late September that both countries were "ready to move further and cut the number of delivery vehicles for strategic offensive armaments by more than three times, and this issue is now being discussed at the negotiating table with our American partners."

He also said that a new Russian-U.S. strategic arms reduction treaty is likely be ready by December this year.

According to a report published by the U.S. State Department in April, as of January 1 Russia had 3,909 nuclear warheads and 814 delivery vehicles, including ground-based intercontinental ballistic missiles (ICBM), submarine launched ballistic missiles (SLBM) and strategic bombers. The same report said the United States had 5,576 warheads and 1,198 delivery vehicles.
