Khalilzad said in a tweet that in recent days, a few commentators have raised questions about the US’s priorities in Afghanistan.
“A peace process that delivers a political settlement is the priority,” Khalilzad clarified.
He added that Afghans want peace above all but wanting peace does not preclude them from demanding preparations for a credible presidential election.
“Election planning must go forward as we pursue the peace Afghans deserve,” he said.
Eighteen presidential candidates are running in the upcoming elections scheduled for September 28.
Khalilzad wrapped up his sixth round of talks with the Taliban in Doha last month where he made “steady but slow” progress on key issues under debate.
