The United States will start the process of pulling out of the Intermediate-Range Nuclear Forces Treaty (INF Treaty) on February 2, the State Department's Under Secretary for Arms Control and International Security Andrea Thompson told reporters on Wednesday, adding that the process was expected to take six months, TASS reported.

According to her, no breakthrough was achieved at Tuesday’s US-Russian consultations in Geneva.

Russian Deputy Foreign Minister Sergei Ryabkov, who headed the Russian delegation to the Geneva meeting, said earlier that Moscow had offered to take measures to raise Washington’s grievances concerning the INF Treaty in return for steps in relation to unmanned aerial vehicles, target missiles and the Mk-41 launching systems but the US was not ready for a specific conversation.

No developments in Russia-US relations yet, says Kremlin aide

"The US tried to make it look like the only issue the Geneva consultations should focus on was the [Russian] 9M729 missile. We cannot accept such an approach, we are ready for dialogue based on the principles of equality and mutual respect, while there can be no ultimatums," Ryabkov said.
