"To achieve a peace agreement, quite a number of issues have to be dealt with", Khalilzad said, stressing two top issues during talks with the Taliban: counterterrorism and a US withdrawal.
Khalilzad said he has pressed the Taliban to agree to a permanent cease-fire as a step toward ending the war, but they have resisted, arguing that it would remove their leverage and reduce the Afghan government's incentive to make concessions in direct negotiations.
"We have a draft of the framework that has to be fleshed out before it becomes an agreement", Khalilzad said at the time.
In the meantime, Khalilzad said the Taliban leaders may participate in future summits in the presence of Afghan government representatives.
The talks, which were held from February 4 to 7, were attended by 40 Afghan politicians, excluding government officials.
He insisted that the Taliban are holding talks with the United States "on their own initiative".
Mujahid said that while the Taliban do not have a codified manifesto, their "clear" objectives were the end of the occupation of Afghanistan, establishment of an Islamic government, establishment of peace and security, reconstruction of Afghanistan and the provision of administrative services.
He also served as the US Ambassadors to Afghanistan and Iraq during the Bush Administration.
Khalilzad is seeking an agreement in which Taliban would negotiate in good faith with the Afghan government and commit to ending any terrorism threat within the country.

"I would be wary of taking that and extrapolating off that and saying they're now on board with the peace process", said Jason Campbell, who was the Pentagon's Afghanistan country director until previous year and is now at the RAND Corporation think tank.
The envoy, Zalmay Khalilzad, said he hopes a final deal is clinched before Afghanistan's presidential election in July.
If there is no progress towards peace, he added, "the elections will take place, and we are doing what we can to support the preparations for a credible election".
U.S. President Donald Trump has repeatedly signaled his intention to wind down America's longest conflict, declaring Tuesday in his State of the Union address that "great nations do not fight endless wars".
Additionally, the Taliban have promised not to provide shelter again to foreign extremists, but experts say they can not be trusted and even now are helping to hide foreign militants.
The Taliban control almost half of Afghanistan, and are more powerful than at any time since the 2001 US-led invasion after the 9/11 terror attacks in 2001.
The US can not be a substitute for decisions that they must make.
In contrast, his assessment of the 18-year US-led military campaign in Afghanistan was far less positive.
The government has criticised the talks from the beginning, by saying that the talks hosted by Russian Federation were against the spirit of Afghan-led and owned peace process. Taliban officials alleged publicly this week that the United States had agreed to remove half of its troops from Afghanistan by May, a statement Khalilzad called false.
