UN special envoy Ismail Ould Cheikh arrived in Yemen's capital Sanaa on Sunday.
On the visit, he will meet with officials from the Houthi militant group and the General People's Congress, the party of the former president, to discuss issues with regard to a new round of peace talks.
The Saba news agency quoted Cheikh as saying, "We came to Sanaa within continuous efforts with the concerned Yemeni factions to hold the new round of peace talks after progress we had lately made at Swiss consultations".
Cheikh is expected to visit the temporary capital the southern city of Aden for meetings with president Abd Rabbuh Mansour Hadi and other officials, sources revealed.
On Saturday, government officials expected the talks, which were scheduled to start in mid-January, to be postponed until the end of the month as news reports said Cheikh suggested the talks be held in Geneva.
The peace talks aim to reach a deal to end the ten-months conflict which has resulted in the worst humanitarian catastrophe even in Yemen's modern history.
Moreover, the talks are expected to produce plans to restore the political process, to implement UN resolutions particularly the resolution 2216 and to address the humanitarian crisis.
Cheikh's visit coincided with ongoing battles between the pro-government and Houthi forces in several provinces including Taiz and Jawf as well as intensified airstrikes by the Saudi-led coalition.
Saba said the coalition struck districts on the outskirts of the capital Sanaa and other provinces including Saada, Hajjah, Taiz and Hodeida injuring civilians and destroying properties.
