Status of U.S.-Russian Nuclear Arms 
Control Talks 
Updated February 3, 2021 
Introduction 
The
 New START Treaty would have expired on February 5, 2021, unless the United States and Russia 
agreed to extend it for up to five years. On January 21, 2021, the Biden Administrati
on announced that it 
would seek a five-year extension of New START, leading to an exchange of diplomatic notes and the 
formal
 extension of the treaty on February 3, 2021. The State Department
 noted that the extension was a 
first step that would provide “the stability and predictability [needed] to enhance and expand discussions 
with Russia and China.” 
The United States and Russia held several meetings during 2020 to discuss New START extension and a 
framework for a future agreement, but did not reach an agreement. In April 2019, President Trump had 
called for expanded arms control efforts with Russia and China, both to capture all types of Russian 
weapons and to bring China into the process. In December 2019, Russian President Vladimir Putin had 
indicated that he would extend New START for five years, without preconditions; Russian officials also 
noted that the countries could address other weapons systems in separate talks after extending New 
START. 
Issues in the Negotiations 
China 
Prior to beginning negotiations with Russia, the U.S. negotiator, Ambassador Marshall Billingslea 
suggested that Washington would not extend New START unless China joined the talks
. He invited China 
to participate, but Chi
na refused, as it has far fewer nuclear weapons than the United States or Russia. He 
then suggested that Russia pressure China to participate. Foreign Minister Ryabkov
 rejected this, noting 
that such a decision would be the “sovereign right of China.” Moreover, Russian officials have
 argued 
that a multilateral treaty should include the United Kingdom and France, a suggestion the United States 
has rejected.

After meeting again in August, Ambassador Billingsle
a reiterated the U.S. goal of including China, but 
indicated that the United States was “not suggesting … that we would amend the New START Treaty to 
include China.” He did not insist that China participate 
before the United States agreed to extend New 
START, but indicated that the framework for the next treaty would have to include a path for China to 
join later. 
The Biden Administration has
 affirmed that the United States will “pursue arms control to reduce the 
dangers from China’s modern and growing nuclear arsenal.” 
Extension and Future Agreement 
In July, Ambassador Billingslea
 stated that the United States would “contemplate an extension” of New 
START if Russia would negotiate an agreement limiting shorter-range nonstrategic nuclear weapons and 
its new types of longer-range strategic systems. During the Jul
y meeting, U.S. and Russian officials did 
not agree on whether to extend New START or on a framework for a future agreement. They established 
working groups to address strategic stability issues, but disagreed on the subjects for some of the groups.  
In August, Ambassador Billingslea
 reiterated that the United States considered New START “deeply 
flawed” and noted that “it is not particularly in the U.S. interest to simply extend that treaty.” He said the 
United States might agree to an extension if Russia signed “a politically binding agreement” that provided 
a framework for a new treaty. The United States presented Russia with detailed proposals to count all 
nuclear warheads and to incorporate more verification and transparency measures than New START. 
Billingslea did not indicate whether, or how, the framework would address Russia’s concerns about U.S. 
weapons in space, U.S. ballistic missile defenses, and other issues that affect strategic stability. Billingslea 
al
so stated that the cost of extending New START could increase if Russia did not accept the U.S. 
proposals before the election, perhaps by including “a lot of the other bad behavior that the Russians are 
engaged in around the world.” He al
so indicated that if Russia did not accept the U.S. proposals, the 
United States would allow New START to lapse and promptly increase the numbers of warheads on its 
strategic forces.  
After reviewing the U.S. proposals, Deputy Foreign Minister Ryabkov
 noted that Russia was ready to 
extend New START but would not do so at any cost. He indicated that Russia would not accept these 
proposals unless the United States also addressed Russian concerns. In August, he
 repeated that Russia “is 
not ready to pay any price” for New START extension. 
In October, the United States
 seemed to narrow its position by
 seeking to pair a short-term extension of 
New START with a short-term freeze on both sides’ nuclear arsenals. The freez
e would accommodate 
U.S. demands for limits on Russian nonstrategic nuclear weapons without addressing other issues in the 
August proposal. After meeting with Deputy Foreign Minister Ryabkov on October 12, Ambassador 
Billingsle
a stated that Presidents Trump and Putin had reached an “agreement in principle” on this deal 
and that he and Ryabkov could complete an agreement quickly. U.S. officials
 believed the two sides could 
reach an agreement in time for the Presidents to sign it before the U.S. election.  
Russian officials disputed this assessment. Deputy Foreign Minister Ryabkov
 called the U.S. reports of a 
quick agreement “an illusion.” H
e stated that the proposed freeze “is unacceptable” because it would not 
address Russian concerns about U.S. weapons. Ryabkov al
so disputed the U.S. assertion that the two 
sides could conclude the agreement before the election. 
On October 16, President Puti
n proposed that the two sides extend New START “unconditionally 
for at least a year” while they continue talks on other arms control issues. President Trump’s National 
Security Advisor, Robert O’Bri
en, dismissed this as a “non-starter” without the freeze on nuclear arsenals, 
and suggested that Russia’s position could lead to “a costly arms race.” On October 20, the Russian 
Foreign Ministry
 stated that Russia 
would accept a one-year freeze on nuclear arsenals if the United States

did not add any conditions to the freeze. Russia also indicated the countries could “hold comprehensive 
bilateral talks” on “all factors that can influence strategic stability” during the extension. The U.S. State 
Department
 welcomed the Russian statement and noted that the “United States is prepared to meet 
immediately to finalize a verifiable agreement.” Russia, however, considered the requirement for 
verification to be an unacceptable condition added to the freeze.  
On October 22, President Puti
n repeated his call to extend the treaty and freeze weapons for a year, 
without preconditions. Deputy Foreign Minister Ryabkov and NSA O’Brien acknowledged that the two 
sides remained at odds over whether to codify verification measures before extending New START or to 
work them out in discussions following the extension. In mid-November, after the U.S. election, Steve 
Biegun, the Deputy Secretary of State,
 noted that the two sides had reached a “plateau” in their 
discussions. Deputy Foreign Minister Ryabkov
 said it was still possible for the two sides to conclude an 
agreement during the Trump Administration, but only if the United States “softened” its position.  
The Biden Administration did not pair the extension of New START with a freeze on all weapons. The 
State Department
 noted, however, that the five-year extension would provide time to “pursue ... arms 
control that addresses all of [Russia’s] nuclear weapons.”
