"It might not," State Department spokesman Patrick Ventrell told reporters when asked if there is a possibility of the US-Taliban talks not happening at all.
"The Secretary (of State) said that over the weekend as well. We don't know one way or another. There were some hopeful signs - a couple of steps forward in terms of opening the office. Clearly, some of the agreement that wasn't adhered to, but we want to see if we can get it back on track, but we'll be clear-eyed and continue to see what can happen," he said.
Such a remark came as the Special US Representative for Afghanistan and Pakistan, James Dobbins, left Doha without having talks with the Taliban.
The Taliban opened its office in Doha last week for talks with the Government of Afghanistan and the United States.
"He (Dobbins) did not meet with the Taliban," Ventrell said in response to a question.
Dobbins is now in Kabul where he met the Afghan President Hamid Karzai. From Afghanistan, he is scheduled to travel to Islamabad and then to New Delhi on Wednesday.
The US is still open to meeting with the Taliban.
"We said that we were open to meeting with the Taliban because we have issues to raise with them directly, but the principal goal is to get Afghans talking to Afghans. So I think part of Ambassador Dobbins' trip was obviously working with the Afghans, and I think they've had some statements as well with the Afghanis over the weekend where they made clear they are open to potentially having this way forward in political dialogue," he said.
