Today, the Saudis officially remain distant from their old allies. Although at one stage they were seen as potential mediators in negotiations between the Taliban and the ousted Afghan government, the smaller Persian Gulf nation of Qatar stepped into that role over the past few years.
This month, after the Taliban took control of the Afghan capital, Kabul, Saudi Arabia's Foreign Ministry released a cautious statement saying, "The kingdom stands with the choices that the Afghan people make without interference."
It's unlikely that Saudi Arabia's historical influence on the Taliban will be revived in any hurry, experts told DW.
The Saudi-US alliance remains important, and the country's ongoing cultural changes also play a part in this. Saudi's controversial crown prince, Mohammed bin Salman, is trying to modernize his countryand the idea of a more liberal and open Saudi Arabia doesn't sit well with lending support to Islamist extremists in other countries
Once allies, Saudi Arabia and the Taliban have been divided by war, betrayal, and 9/11. As Afghanistan changes and Middle East relations shift, the two won't rekindle ties, but another nation is looking closely at Kabul.
