Afghan Taliban officials were due in Pakistan on Wednesday, the insurgent group said, as the top US diplomat involved in talks with the militants also met government officials there, although it was not known if the Taliban and US official would meet.

The Taliban delegation led by Mullah Abdul Ghani Baradar, one of the group's founders, was due to discuss "important issues" with Pakistani officials in the capital, Islamabad, Taliban spokesman Suhail Shaheen said on Twitter.

The Taliban visit, the latest stop on a tour of regional powers, comes after efforts by the militants and the United States to reach a deal allowing for the withdrawal of US-led foreign forces broke down last month.

The top US negotiator in the talks, Special Representative for Afghanistan Zalmay Khalilzad, met Pakistani counterparts in Islamabad this week, following discussions between US President Donald Trump and Pakistani Prime Minister Imran Khan in the United States the previous week.

"These consultations follow discussions held between the United States and Pakistan during the United Nations General Assembly in New York last week," said a spokesman for the US Embassy in Islamabad via email.

The spokesman did not say if Khalilzad was still in Pakistan on Wednesday or if he planned to meet the Taliban officials.

The United States has long considered Pakistani cooperation as crucial to efforts to end war in Afghanistan.

US President Donald Trump last month halted the talks with the Taliban aimed at striking a deal allowing US and other foreign troops to withdraw in exchange for Taliban security guarantees, following the death of a US solder and 11 others in a Taliban bomb attack in Kabul.

The Taliban delegation would inform Pakistan's leadership of the factors that derailed the talks, said a Taliban official, who declined to be identified.

PROGRESS ON PEACE?

The US and Taliban said last month, shortly before talks broke off, that they were close to reaching a deal, despite concern among some US security officials and within the Afghan government that a US withdrawal could plunge the country into even more conflict and open the way for a resurgence of Islamist militant factions.

The Taliban also planned to follow up on Khan's recent comments, that he would try to convince Trump to resume the talks, the Taliban official said.

A government source in Pakistan who declined to be identified told Reuters the Taliban would arrive on Wednesday evening and meet Khan.

Sediq Sediqqi, a spokesman for Afghan President Ashraf Ghani said on Twitter that the Afghan government should be involved in any peace process.

"No progress will be imminent if a peace process is not owned and led by the Afghan government," he said.

The Taliban have refused to negotiate with the Afghan government, dismissing it as a US puppet.

Taliban officials have in recent days visited Russia, China and Iran.

Pakistan supported the Taliban from the group's founding in the midst of Afghanistan's civil war in the early 1990s.

The United States and the US-backed Afghan government have for years suspected Pakistan has maintained its support for the militants, as a tool to block the spread of Indian influence in Afghanistan, despite Pakistani denials.
