Hi Bardo Eagle,
Maybe yes, maybe no. The fact 2 different things happen in the same time line in different parts of the world doesn't necessarily mean they are connected, but i see your point.
I have grown green pure Vietnameses, Dalat, Vietnam Black, many pure Thais and i find some similarities between Green Haze and some SE Asian green sativa landraces (lime/lemony, spicy and woody terpenes, burnt hair and uplifting cerebral non ceiling effects, similar high THC chemotypes with almost null CBD content, similar behaviour and structures, flowering times, etc ...), but i have never found a green SE Asian sativa that in pure form produces loud incense, i have only found strong incensey sativa landraces in Central American sativa populations and in Nepalese sativas, also in some Indian sativas.
Green Vietnameses and green Thais are highly related, it's what i call the 'classic green SE Asian phenotype', it's an archetype expression widely spread in the lowlands of many SE Asian countries. Northern Laotians for example are a different thing.
Probably not even the Haze brothers knew for sure the exact origins of the landrace sativas they used to produce their Haze. I think they got their seeds from imported weed and dealers like to lie, especially to increase prices, if only one person in the smuggling chain lied about the origins then all the people after that can be wrong, and seems Haze brothers didn't collect the seeds in person in the tropics.
So, who really knows ? I'm not going to pretend to know it for sure, but based on my personal experience growing both: pure Haze and many tropical sativa landraces from America and SE Asia, i would bet Haze is mainly old Colombian, or an American sativa x SE Asian sativa of some sort. Genetic analyses seem to indicate the first, i did my part sending samples of our Green Haze and Purple Haze mothers for genetic analyses, and by sharing the results with the community, they are publicly available. Hope others do it with legit Haze lines, genetic analyses are the only way to shed some light and science about this topic, instead of all this endless chatting about Haze origins, this discussion seems to arise lots of passions, but also lot of garbage, and i don't have the time neither the mood for ego fights, as it is happening in other threads, here and in other forums.

Days ago I realized that Haze was bred circa in 1970, concurrently with the Vietnam war,maybe some soldier bring Vietnamese landrace home and start to spread,the Haze Brothers start to breeding and /or cross to other landrace( maybe colombian). Vietnamese Landraces are the green part, and the purple part Colombian or Vietnam purple pheno.
Not thai but Vietnamese
Old school tropical sativa at its best.
... having now bigger space and my passion/journey through hazey hybrids led me to end up here!
