MOSCOW. Sept 18 (Interfax) - Robert O'Brien's appointment as the new national security advisor of the United States may bring about progress in the extension of the U.S.-Russian Strategic Arms Reduction Treaty (New START), State Duma Foreign Affairs Committee Chairman Leonid Slutsky said.
"We expect progress in the extension of New START with new National Security Advisor O'Brien," Slutsky told Interfax.
The New START's extension is a matter of global security, and "responsibility for it rests with the U.S. and Russia," he said.
