Literally three countries every recognised the Taliban government in Afghanistan. And they eventually had crap relations with two of them, apparently a little matter of assaulting Saudi Arabian and United Arab Emirates dignitaries and visitors.
Relations with Iran were poor, as a result of murdering a whole pile of Iranian diplomats in a basement one night.
The Taliban were invited to visit the United States and were on some kind of verge of diplomatic relations. This was largely American business and geopolitical strategizing. Afghanistan had mineral resources American companies wanted, heroin which the US government wanted to suppress, and was a route for a pipeline. So it's possible that if there was a large scale commercial operation through Afghanistan, say a pipeline, then there would be some formal relationship with the US.
Apart from that, the Taliban's only recognition came from their benefactor and supporter, Pakistan. Pakistan was nominally an American Ally, mainly because India wasn't.
It's likely that Taliban foreign policy would be primitive and sloppy, but most likely it would be pro-Pakistan, anti-Iranian, anti-Russian (vehemently), possibly pro-Chinese, likely pro-American, Anti-Israel, nominally pro-Arab, and militantly crazy Islamic.
I don't think you'd see a lot of diplomatic relationships though.
