The announcement by Syrian Foreign Minister Walid Muallem in Moscow could mark another diplomatic success for Russia after the Kremlin managed to convince its ally Damascus to renounce its chemical weapons in order to avert imminent US air strikes.
It also came just as the war-torn country's divided opposition prepared to hold decisive talks in Istanbul on whether to join a peace conference that is due to begin on Wednesday in Switzerland.
"I informed (Russian Foreign Minister Sergei) Lavrov of our principled position in favour of an agreement to exchange those held in Syrian prisons for those taken by the other side," Muallem said following talks with his Russian counterpart in a government mansion in the heart of Moscow.
"We are ready to exchange lists and develop the necessary mechanism for accomplishing these goals," Muallem said in remarks translated from Arabic into Russian.
Syria "will take part in Geneva II and make every effort to ensure this event is a success and meets the aspirations of the Syrian people and the direct orders of President Bashar al-Assad," said Muallem.
