Syria's main opposition group has called for face-to-face discussions with government representatives, as a new round of talks in Geneva begins one year after meetings in the Swiss city fell apart.
"We ask for direct negotiations ... It would save time and be proof of seriousness instead of negotiating in [separate] rooms," Salem al-Meslet, spokesman for the High Negotiations Committee (HNC) umbrella group, told reporters.
The talks began on Thursday.
During three previous rounds of talks in Geneva last year, the two sides never sat down at the same table, instead leaving UN mediator Staffan de Mistura to shuttle between them.
"If the regime's side is here for serious talks, it shouldn’t hesitate or run away from face-to-face talks. If the purpose of the talks are to bring peace to Syria, and to stop the bloodshed, we are ready for it," Yehya al-Aridi, advisor to the HNC, Syria's main opposition umbrella, told Al Jazeera as the talks kicked off at the United Nations headquarters.
Still, the opposition official said the rebels would not quit the talks should the Syrian government delegation refuses direct negotiations.
"We are ready to go anywhere in the world in order to bring Syria back to life," said Aridi.
De Mistura has played down expectations for major progress in the negotiations.
"Am I expecting a breakthrough? No, I am not expecting a breakthrough," he told journalists at the UN headquarters on Wednesday, a day before the start of the fourth round of talks aimed at finding a political solution to Syria's long-running conflict.
Though the Geneva talks are seen as the most serious diplomatic effort in months, disputes over the agenda and long-standing disagreements between the opposition and the government on the future of Syria have cast doubts on whether any progress will be achieved.

De Mistura said he was determined to maintain "a very proactive momentum" to allow for political discussions on governance, a new constitution and elections under UN supervision, based on the UN Security Council Resolution 2254.
In recent days, however, the UN mediator has shied away from using the phrase "political transition" - a term the Syrian opposition equates with the removal of President Bashar al-Assad - to describe the goal of the talks.
During previous rounds of UN-led negotiations, the Syrian government categorically refused to discuss Assad's fate - the main bone of contention between the two sides.
The intra-Syrian talks come on the heels of multilateral meetings - facilitated by Russia, Turkey and Iran - in the Kazakh capital of Astana to consolidate a fragile nationwide truce brokered by Russia and Turkey, in place since December 30.
The negotiations in Astana were meant to pave the way towards political negotiations in Geneva, but the ceasefire has steadily fallen apart over the past month, while promises to establish a monitoring mechanism were not fulfilled.
Officials from the opposition delegation, split between military and political representatives, similarly expressed little hope for the talks.
"When the adherence to the ceasefire is not there," and when there are "games being played at the level of international terms of reference to political transition and a constitution [...] then the negotiations are not encouraging," Aridi told Al Jazeera.
"Things are getting complicated further and further, with conflicting agendas. Not only from the main two banks of the conflict, but also within our bank," he told Al Jazeera.
Infighting within rebel ranks has severely weakened and divided the Syrian opposition over the past month.
That, coupled with uncertainty surrounding US policy on Syria under President Donald Trump, a shift in the priorities of Turkey - traditionally a backer of Syrian rebel groups - and Russia's 2015 military intervention in support of Assad, has left the opposition with little leverage both politically and militarily.
"There are no solutions in sight now. The reality on the ground is getting worse," Fares Bayoush, a Free Syrian Army commander, told Al Jazeera.
Omar Kouch, a Syrian analyst, said that while the presence of a ceasefire makes this round of talks markedly different, "there are no indications that the fourth Geneva talks will be serious about finding a solution".
Kouch said the chances for reaching a solution are slim, citing the continued government offensives on several areas across Syria, the absence of the dominant Syrian Kurdish faction - the Democratic Unity Party (PYD) - at the negotiating table and major divisions within the opposition.
"As in every round of talks, we start with a lot of hope to find a solution, but then the talks are over and nothing is accomplished. In fact, things get worse," he told Al Jazeera.
With both sides seemingly unwilling to make political concessions, it is unclear how the negotiations could bridge the divide and find a solution.
Still, the Syrian opposition is expected to press for the consolidation of the ceasefire, the release of prisoners, the lifting the blockades over besieged areas and securing a political transition from Assad’s government.
"The main thing is that there is no submission. We are trying very hard, to decrease the losses," said Aridi.
