The suggestion by France last week of setting up protected escape routes for Syrian civilians fleeing the unrest "is an interesting idea," Calmy-Rey told the press club in Geneva, according to the ATS news agency.
"The humanitarian situation is deteriorating. We will examine the idea of humanitarian corridors," she said. "If the project materialises, if it has positive effects, it will be a good thing."
Investigators appointed by the United Nations said Monday that Syrian security forces shot and abused anti-regime demonstrators on orders hailing from the top of Bashar al-Assad's regime.
The brutal crackdown on anti-regime protestors has killed at least 3,500 people since March, according to UN estimates.
UN humanitarian chief Valerie Amos said Friday that international help is needed to feed 1.5 million people in crisis-torn Syria, but that humanitarian corridors were not yet justified.
