The Kremlin cannot comment on its position regarding the New START treaty extension yet, as there is a need to update information on the parties’ stance, and the negotiations will depend on the US stance on the issue, Kremlin spokesman Dmitry Peskov said Friday.

White House Press Secretary Sean Spicer also refused Thursday to comment on allegations made by anonymous US officials claiming that Trump spoke negatively about the New START treaty during his January 28 phone call with Russian President Vladimir Putin.

“I would not formulate any positions as of now. We had a certain pause in strategic security dialogue, therefore, of course, so to speak, in terms of the break there is a need for a certain update, a mutual information update on the positions. This [dialogue] depends on our US partners. And we will obviously need contacts on the matter,” Peskov told reporters.

Peskov said he would not comment on reports of US President Donald Trump criticizing the New Strategic Arms Reduction Treaty (START) to Putin.

“I could not confirm this. Everything we felt was needed to report on the results of the telephone conversation we have reported. There is nothing more to add,” Peskov told reporters.

The treaty with the formal name Measures for the Further Reduction and Limitation of Strategic Offensive Arms was signed between Russia and the United States in April 2010 in Prague, and entered into force on February 5, 2011. The Treaty’s duration is ten years — until 2021, unless superseded by a subsequent agreement. Under the Treaty, the United States and Russia must meet the Treaty’s central limits on strategic arms by February 5, 2018, that is seven years from the date the Treaty entered into force.

The Strategic Arms Reduction Treaty treaty requires the parties to the contract to reduce and limit the number of deployed and non-deployed strategic offensive arms. It stipulates that the parties may agree to extend the treaty for a period of no more than five years.
