Assad willing to eliminate chemical weapons within a year
Assad says destruction of chemical weapons need about one billion dollars and is very detrimental to the environment.
Syrian President Bashar al-Assad has said he is committed to destroy his country's chemical weapons but warned it could take about a year.
Assad again denied claims that his forces were responsible for a deadly chemical attack near Damascus on 21 August.
The Syria disarmament plan was unveiled by the US and Russia last weekend.
The West wants the deal enshrined in a UN resolution backed by the threat of military force, but Russia objects.
Damascus - backed by Moscow - has insisted that rebel forces carried out last month's attack in the Ghouta area.
Referring to the issue of destroying Syria's stockpiles of chemical weapons, Assad said it was "a very complicated operation, technically. And it needs a lot of money, some estimates say about a billion!”
"So it depends, you have to ask the experts what they mean by quickly. It has a certain schedule. It needs a year, or maybe a little bit more," Assad said in an interview with Fox News.
When asked whether he would be willing to hand over chemical weapons to the US, President Assad said: "It needs about one billion. It is very detrimental to the environment. If the American administration is ready to pay this money and take the responsibility of bringing toxic materials to the United States, why don't they do it?"
Assad also used the one-hour interview recorded in Damascus to criticise the US stance in the Syrian crisis.
Unlike the Russians, he said, Washington had tried to get involved in Syria's leadership and governance.
He argued that if there was mutual respect, there would not be any problems.
"Listen to your people. Follow the common sense of your people," he said, in an apparent reference to US President Barack Obama.
Assad's comments come shortly after a senior Russian diplomat said Damascus would fulfil its commitment to eliminate its chemical weapons by mid-2014.
More than 100,000 people have been killed since Syria's civil war began in early 2011, according to the UN.
Millions have fled the country and millions more have been left homeless.
