UN special envoy Ismail Ould Cheikh is expected to arrive in Yemen in coming hours, officials in the temporary capital of Aden said on Saturday.
On his visit, Cheikh will meet with president Abd Rabbuh Mansour Hadi to discuss arrangements for the new round of peace talks.
The talks aim to put an end to the armed conflict and establish plans to restore the political process.
The official Saba news agency reported that Cheikh has suggested the talks be held in Geneva.
Meanwhile, news reports said the talks are expected to be postponed to the end of the month.
Last month after the Yemeni factions failed to reach a deal to end the conflict, Cheikh announced the new talks were scheduled to start in mid-January.

"He also has received troubling reports of the use of cluster munitions in attacks on Sana’a on 6 January in several locations. The use of cluster munitions in populated areas may amount to a war crime due to their indiscriminate nature," it said.
Moreover, Ban urged all parties of to respect their obligations under international human rights law and international humanitarian law, which prohibit attacks on civilians and civilian infrastructure and that they show good will in order to convene a new round of peace talks as soon as possible, according to the statement.
