President Ashraf Ghani and Abdullah Abdullah, who has become chief High Council for National Reconciliation, should not repeat mistakes in governing that existed under the National Unity Government, US special envoy Zalmay Khalilzad said on Sunday.

Khalilzad said that the US is prepared to partner with the new government in a peace process that ends the war.
"That process must be based on timely implementation of commitments made to date. Both leaders should not repeat mistakes in governing that existed under NUG, as Afghans negotiated this govt," Khalilzad said on Twitter.
He urged Abdullah to move forward with "full speed and urgency."
"It is high time to take seriously the resolve of the Afghan people, and the world, to finally see an end to this conflict. Dr. Abdullah must move forward with full speed and urgency, and be sincerely supported therein by the current Afghan government," Khalilzad said.
Meanwhile, US Secretary of State in a phone call with Ghani and Abdullah congratulated them for reaching the agreement and noted that he regretted the time lost during the political impasse.
He reiterated that the priority for the United States remains a political settlement to end the conflict and welcomed the "commitment by the two leaders to act immediately in support of prompt entry into intra-Afghan negotiations," the US State Department said.
NATO Secretary-General Jens Stoltenberg also welcomed the decision by Afghanistan’s political leaders to resolve their differences and join efforts to form an inclusive government. "NATO remains committed to supporting Afghanistan build lasting peace," he said.
The UN Assistance Mission in Afghanistan (UNAMA) also welcomed the agreement.
"The Mission acknowledges that both sides had to make compromises to reach this important agreement," UNAMA said. "It is now hoped that the spirit of cooperation will continue, with all elements in government working together to strengthen progress in good governance, the rule of law, and anti-corruption, and to protect the rights of all citizens while continuing the advancement of Afghan women."
