Russian President Vladimir Putin yesterday made a shock announcement that he had ordered the withdrawal of "the main part" of Russia's forces after talks with long-standing ally, Syrian President Bashar al-Assad.
"The announcement by President Putin on the very day of the beginning of this round of intra-Syrian talks in Geneva is a significant development," Staffan de Mistura said in a statement read by his spokesman Ahmad Fawzi.
"We hope (this) will have a positive impact on the progress of the negotiations in Geneva aimed at achieving a political solution of the Syrian conflict and a peaceful political transition in the country," he added.
Putin's announcement came ahead of the fifth anniversary of the start of Syria's brutal conflict, which has left more than 270,000 dead and forced millions to flee their homes.
"Today is an important day," Fawzi said.
He pointed out that it was not only the fifth anniversary of the start of Syria's "tragedy" but also the 18th day of a partial truce, which he said was "fragile, vulnerable, but holding by and large."
And hopes for a breakthrough at the Geneva talks remained remote, with both sides locked in a bitter dispute over Assad's future.
