Russia sees a pressing need for security talks with the United States but they must be "comprehensive" and include the subject of Ukraine, the Kremlin said on Friday.
"It is impossible to rip out any individual segments from the general complex of accumulated problems, and we will not do this," Kremlin spokesman Dmitry Peskov said when asked if Moscow was ready to talk to Washington about nuclear risks.
"So we are open to dialogue, but to a broad comprehensive dialogue that covers all dimensions, including the current dimension related to the conflict around Ukraine, related to the direct involvement of the USA in this conflict," Peskov told reporters.
The United States rejects Russia's contention that by arming Ukraine it has become a direct protagonist in a war aimed at inflicting a crushing "strategic defeat" on Moscow. The U.S. says any negotiations over the war are a matter for Ukraine.
