The United States sees value in the New Strategic Arms Reduction Treaty (New START) with Russia, despite Washington's concerns about Moscow's track record on arms control and other issues, senior U.S. officials said Friday.

The remarks by the Trump administration officials, speaking to reporters on condition of anonymity, suggest the treaty will remain in force and the door remains open to pursuing an extension of the accord, which is set to expire in 2021.

The New START gives both countries until February 2018 to reduce their deployed strategic nuclear warheads to no more than 1,550, the lowest level in decades. It also limits deployed land- and submarine-based missiles and nuclear-capable bombers.
