In a separate interview, Haley told CBS News that new sanctions against Russian Federation, which has forces in Syria supporting the Assad regime, would be announced Monday that would "go directly to any sort of companies that were dealing with equipment related to Assad and chemical weapons use".
"In the United States administration there are specific people who it is possible to talk with", said Mr Ermakov, head of the ministry's department for non-proliferation and arms control.
Nikki Haley, the USA ambassador to the United Nations, warned Syrian President Bashar al-Assad on Sunday that the US would launch new missile strikes against his regime if he carries out another chemical weapons attack. The Western states have accused forces of Syrian President Bashar Assad of an attack with the use of chemical weapons in Duma.
Appearing on Fox News Sunday, U.S. Ambassador to the United Nations Nikki Haley said in a military context the president's declaration of "mission accomplished" refers only to the "task now in front of you" and the United States will continue to monitor Assad's use of chemical weapons and are prepared to respond with further action in the form of additional military action.
"We are determined to completely crush ISIS and create the conditions that will prevent its return." she said, referring to the Islamic State extremist group.
"We of course know our work in Syria is not done", Haley said.
The Syrian Armed Forces later said the US and its Western allies fired a total of one-hundred-and-ten missiles from manned aircraft and ships. The Pentagon confirmed the airstrikes hit three sites: a scientific research facility in the capital, Damascus, and chemical weapons storage facilities, as well as an important command post near Homs.
Haley warned that the United States was "locked and loaded" if any new chemical attack was carried out in Syria.
With Russian involvement in Syria and Moscow condemning Saturday's allied missile strike, Haley acknowledged that U.S. The legality of the air strikes under global law, however, remains questionable.
The action was in response to a recent deadly attack in the town of Douma.
The Russians, however, say 71 missiles were shot down by Syrian systems - many of them older Soviet-era defences.
New Western air strikes in Syria would provoke "chaos" in global relations, Russian President Vladimir Putin told his Iranian counterpart on Sunday.
