Afghan government, U.S. and Turkish officials had said they intended to begin the conference Friday. It was to last 10 days.
No new date for the Turkey conference was set but time is running out on a May 1 deadline for the withdrawal of U.S. and NATO troops from Afghanistan in keeping with a deal the Trump administration made with the Taliban more than a year ago.
Until now the Taliban have refused, warning of “consequences” if Washington reneges on the deal and the withdrawal timeline.
Last month, Blinken gave both the Taliban and the Afghan government an eight-page proposed peace plan, which they were to discuss, revise and review and come to Turkey ready to cobble together an agreement.
In an audio message to The Associated Press, Taliban spokesman Mohammad Naeem said the Islamic Emirate — the name the Taliban gave their government — was not ready to attend this week’s planned meeting in Turkey. He said the insurgent group was still discussing the U.S.-proffered peace agreement. He later shared his audio recording on a What's App group.
Naeem said attendance at the conference and the Blinken peace proposal were being discussed “and whenever the discussion is completed we will share our final decision.”
Blinken's peace plan called for protection of the rights of women and minorities and allowed for constitutional reform. It also called for the establishment of an interim administration, to be known as a "Peace Government." There would also be an Islamic Advisory Council which would advise on all laws to ensure they are kept within Islamic tenets, an apparent concession to the Taliban.
Afghan President Ashraf Ghani, who has grown increasingly isolated in Kabul as his political opponents accuse him of clinging to power, offered an alternative to Blinken's proposal. Ghani supported an interim government that he would head until elections could be held within months.
The Taliban have made it clear they would not accept a government headed by Ghani, but they have yet to offer an alternative to Binken's proposal.
Blinken announced the Turkey meeting in a sharply worded letter to Ghani and other Afghan leaders. In that letter Blinken warned that a U.S. withdrawal without a political settlement would leave Ghani's government vulnerable to Taliban gains.
“I am concerned that the security situation will worsen and the Taliban will make rapid territorial gains,” Blinken said in the letter.
Washington's peace envoy, Zalmay Khalilzad, the man who negotiated the U.S. troop withdrawal under President Trump, has been shuttling between Doha, where the Taliban maintain a political office, and Kabul.
The U.S. Embassy in Kabul on Monday said Khalilzad had spent four days in the Afghan capital meeting with government officials and civil society leaders, underscoring “why it is important that both sides accelerate the peace process.”
“In all his meetings Ambassador Khalilzad was encouraged by the shared vision for an Istanbul conference that advances prospects for a just and durable peace to in Afghanistan,” said the statement, even as the Taliban made it clear they were not ready to attend.
