The two top diplomats are in daily contact on the matter and sealed a deal in Geneva last weekend aimed at dismantling the Damascus regime's arsenal of these types of banned arms.
    
While welcoming his Dutch counterpart Frans Timmermans to the State Department, Kerry told reporters that he had had a fairly long phone conversation with Lavrov earlier in the day.
    
"We talked about the cooperation on which we both agreed to continue to provide, moving not only towards the adoption of the OPCW (Organization for the Prohibition of Chemical Weapons) rules and regulations, but also a resolution that is firm and strong within the United Nations," Kerry said.
    
"We will continue to work on that," he added. Timmermans, meanwhile, said the Netherlands and the United States were ‘exactly on the same page.’
    
"In the UN, we see eye to eye as to the content of the United Nations Security Council resolution, which should be very firm on making sure that Assad, who doesn't have a track record of actually doing what he promises, does what he has promised now," he said, referring to Syrian President Bashar al-Assad.
    
Yesterday, Kerry said that the UN Security Council must be prepared to agree to a binding resolution on Syria's chemical weapons next week.
    
The five permanent members of the panel - the United States, China, Russia, France and Britain - have been wrangling over the text of the resolution since Monday in an effort to find common ground.
    
Russia, a key ally of Damascus, opposes all references to a possible use of force. Just as Kerry and Timmermans were speaking, the Organization for the Prohibition of Chemical Weapons said it had received initial details on Syria's program and arsenal, which it has been tasked with dismantling.

Syria submits chemical details to watchdog
    
Syria has begun supplying details of its chemical arsenal, the world's chemical weapons watchdog said, as the rebels agreed a truce with jihadists in a key border town.
    
A senior Syrian official, meanwhile, said that Damascus wanted a ceasefire in the 30-month war, which has reportedly killed more than 1,10,000 people and forced more than two million to flee.
    
Hours before a deadline for Syrian President Bashar al-Assad's regime to provide details on its arsenal, the Hague-based group tasked with dismantling the arms said it has received an initial report.
    
"The Organization for the Prohibition of Chemical Weapons has received an initial disclosure from the Syrian government of its chemical weapons programme," an OPCW statement said.
    
Its Technical Secretariat is now examining the details, it said. A United Nations diplomat said the OPCW had received the Syrian declaration yesterday. "It is quite lengthy," he said.
    
The organization has postponed a meeting of its Executive Council set for Sunday that had been due to discuss how to dismantle Syria's chemical weapons programme.
    
Damascus had time until Saturday to supply details of its arsenal, in line with a US-Russian plan that helped prevent military action on regime targets following a chemical attack last month that killed hundreds of people.
    
The plan stipulates that Assad's regime hand over its chemical weapons and facilities, which would be destroyed by mid-2014.
    
US Secretary of State John Kerry said that he and his Russian counterpart Sergei Lavrov spoke on the telephone today about a ‘strong’ UN Security Council resolution on ridding Syria of chemical weapons.
    
"We talked about the cooperation which we both agreed to continue to provide, moving not only towards the adoption of the OPCW rules and regulations, but also a resolution that is firm and strong within the United Nations," Kerry said.
    
"We will continue to work on that," he added. Kerry had earlier said that the Security Council must be prepared to agree to a binding resolution next week.
    
The five permanent members of the panel - the US, China, Russia, France and Britain - have been wrangling over the text of the resolution since Monday in an effort to find common ground. Russia, a key ally of Damascus, opposes all references to a possible use of force.
    
Meanwhile, the Syrian Observatory for Human Rights said that the Northern Storm brigade, which is loyal to Free Syrian Army rebels and was based in Azaz, has agreed to a truce with Islamic State of Iraq and the Levant, which fought fiercely for the town of Azaz on the Turkish border.
