Is a rift between Pakistan, the Afghan Taliban imminent?

Al Jazeera :
When the Taliban took over the Afghan capital, Kabul, in August last year, many in Islamabad cheered. The collapse of the Western-backed Afghan government was seen as an opportunity to reset relations between the two countries, which had grown strained under Afghan President Ashraf Ghani. After the formation of the Taliban government, Islamabad became one of its main supporters on the international scene, calling for its recognition and for urgent financial assistance.
In recent months, however, signs have emerged of cracks in the otherwise amicable relations between the two. Disagreements over the demarcation of the Afghanistan-Pakistan border and Afghan Taliban support for the Tehreek-e-Taliban Pakistan (TTP) have caused tensions.
In early September, while the Taliban was deliberating the makeup of its government, Pakistan’s former intelligence chief Lieutenant General Faiz Hameed paid a visit to Kabul. According to Afghan and Pakistani sources, Hameed was able to influence the decisions on the final makeup of the interim cabinet to favour pro-Pakistani figures from the Haqqani Network and prevent Mullah Ghani Baradar from taking the head of government position.
Bardar, a prominent Taliban leader, is perceived to harbour hostility towards Islamabad, given his imprisonment by the Pakistani authorities between 2010 and 2018. A government headed by him would not have been as friendly to Pakistan. By contrast, the Haqqani Network, which took key cabinet portfolios, including the ministries of interior, communications, education and refugee and repatriation, are considered close to Islamabad.
While Pakistan’s ability to sway the Taliban government formation process reflects the extent of its influence in Kabul, it has also caused resentment among certain circles within the leadership of the group.
This was made apparent in late December and early January when Afghan border guards forced Pakistani workers to stop fencing the border between the two countries. The incident was followed by an exchange of public statements by Afghan and Pakistani officials.
“The issue of the Durand Line is still an unresolved one, while the construction of fencing itself creates rifts within a nation spread across both sides of the border. It amounts to dividing a nation,” Afghan Information Minister and Chief Spokesman Zabihullah Mujahid said in an interview for a Pashto-language YouTube channel, referring to the Pashtun community, the biggest ethnic group in Afghanistan and the second-biggest one in Pakistan.
