Envoy Staffan de Mistura on Thursday "wanted to ensure that the talks will start a political process leading to a real political transition", Xinhua quoted Farhan Haq, the deputy UN spokesman, as saying.
The newly announced date for the resumption of the Syria talks is four days behind the original schedule. The second round of Syrian peace talks was originally slated for April 9.
In the coming days, de Mistura plans to travel to Damascus and Tehran, and also to meet with Turkish, Saudi and other officials, before returning to Geneva in the middle of next week, Haq said.
While in Syria, he expects to meet the foreign minister and deputy foreign minister, Haq said.
"The special envoy added that the proceedings in Geneva are expected once more to start with proximity talks," Haq said.
The first round of intra-Syrian peace talks in Geneva wrapped up on March 24 with a paper of 12 points of commonalities being delivered to both sides for further consideration by de Mistura.
The UN said a more positive atmosphere at the March round was helped by a cease-fire in Syria, which was declared on February 27 and remains broadly in place, despite multiple reported violations.
More than 270,000 people have been reportedly killed in Syria and millions have fled their homes since the conflict broke out in March 2011. (IANS)
