The United States has told Russia it will no longer share data on its strategic nuclear forces, due to Moscow's declaration last month to suspend its participation in the New START treaty, a National Security Council spokesperson said Tuesday.

"This was done in response to Russia refusing first to provide data," the spokesperson said. "We would gladly provide this data if Russia would adhere to the treaty but see no reason to incentivize Russia to avoid complying with the treaty by sharing data they want to have."

Under the last remaining nuclear arms control pact between the United States and Russia, the two were obligated to exchange comprehensive data, including the numbers and characteristics of weapons systems, every six months.

The accord, which entered into force in 2011, limits each side to no more than 1,550 deployed nuclear warheads and requires a range of verification steps such as onsite inspections.

As tensions between the two countries remain high, Russian President Vladimir Putin announced Moscow's suspension from the treaty in his annual state-of-the-nation address on Feb. 21, just days before the first anniversary of the start of its war in Ukraine.
