MOSCOW -- Russia has postponed a round of nuclear arms control talks with the United States set for this week because of stark differences in approach and tensions over Ukraine, a senior Russian diplomat said Tuesday.
Deputy Foreign Minister Sergei Ryabkov said the decision to put off the talks that were scheduled to start Tuesday in Cairo was made at the political level.
"We faced a situation when our U.S. colleagues not just demonstrated their reluctance to listen to our signals and reckon with our priorities, but also acted in the opposite way," Ryabkov told reporters in Moscow.
Ryabkov claimed the U.S. wanted to focus solely on resuming inspections under the New Strategic Arms Reduction Treaty and stonewalled Moscow's request to also discuss specifics related to the weapons count under the strategic arms reduction pact.
Moscow decided to unilaterally postpone the Cairo talks and would propose new dates, the U.S. State Department reported Monday.
"The United States is ready to reschedule at the earliest possible date as resuming inspections is a priority for sustaining the treaty as an instrument of stability," the agency said.
This week's meeting of the Bilateral Consultative Commission established under the New Strategic Arms Reduction Treaty would have been the first in more than a year.
Russia has protested the deliveries of Western weapons to Ukraine. Ryabkov said the situation in Ukraine contributed to Moscow's decision to delay the talks.
"Arms control and the dialogue in this sphere can't be immune to what is happening around, and the bigger picture, which is quite complicated and largely disquieting, has played a role," he said.
The treaty, signed in 2010 by President Barack Obama and Russian President Dmitry Medvedev, limits each country to no more than 1,550 deployed nuclear warheads and 700 deployed missiles and bombers. The agreement envisages sweeping on-site inspections to verify compliance.
Just days before the treaty was due to expire in February 2021, Russia and the United States agreed to extend it for another five years.
In August, Russia declared a temporary halt on U.S. inspections, charging that visa restrictions, sanctions on Russian flights imposed by the U.S. and its allies, and other obstacles made it difficult for Russian military experts to visit U.S. nuclear weapons sites, giving the U.S. "unilateral advantages."
At the same time, Moscow said "highly values" the treaty and held the door open for resuming inspections in the future.
While Russia and the U.S. have suspended mutual inspections under the treaty since the start of the covid-19 pandemic, Moscow's move raised new uncertainty about the pact's future.
Ryabkov noted that there was mutual agreement over the temporary halt on inspections that was in full compliance with the treaty and emphasized the pact's importance.
