MOSCOW (Reuters) - Russia and the United States have made significant progress in talks on a new nuclear arms reduction agreement, Russian Foreign Minister Sergei Lavrov said on Tuesday after talks with U.S. Secretary of State Hillary Clinton.
President Barack Obama and Kremlin chief Dmitry Medvedev agreed in July the outlines of a preliminary deal to replace the landmark 1991 Strategic Arms Reduction Treaty (START-1) but negotiators are facing a host of technical issues in talks.
