Following Russia’s decree to end their joint nuclear deweaponization program with the US, the US State Department announced Monday that Washington has suspended bilateral contact with Moscow.

(VERO BEACH, FL) America has “suspended” bilateral contacts with Russia over the Syrian crisis, the US State Department said.

US officials had threatened for a week to withdraw from the Syrian peace process, after the latest ceasefire negotiated by Foreign Minister Sergey Lavrov and Secretary of State John Kerry collapsed amid bloody fighting.

While contacts between US and Russian military to “deconflict” encounters between their aircraft in Syrian skies will continue, the US is withdrawing personnel that was dispatched for the purpose of setting up the Joint Implementation Center (JIC) for the ceasefire, agencies reported citing the State Department.

There is “nothing more for the US and Russia to talk about” in Syria, White House spokesman Josh Earnest told reporters on Monday.

Washington has dragged its feet on setting up the JIC, however, with State Department spokesman John Kirby telling reporters on September 16 that its establishment was contingent on humanitarian aid reaching Aleppo, while the Chairman of the Joint Chiefs of Staff, General Joseph Dunford, told lawmakers the US had “no intention of having an intelligence-sharing agreement with the Russians.”

The JIC is located in Geneva, Switzerland.

On Monday, Russian President Vladimir Putin suspended Moscow’s participation in a program for disposing of plutoniumfrom decommissioned nuclear warheads, citing “the radical change in the environment, a threat to strategic stability posed by the hostile actions of the US against Russia, and the inability of the US to deliver on the obligation to dispose of excessive weapons plutonium under international treaties.”

The White House called the decision “disappointing.”
