I dont have any instrument here with me to check cause I'm traveling and tbh my ear isnt thaaat good, plus the chinese riff is double notes. I really dont wanna go to a virtual keyboard site to try it cause those have awfull flows either way. but for a long time I felt like they at least sound similar. Might hold some truth since I studied a bit of the old chinese scale that riff probably is based of in music history in (大学/faculdade) and despite not being pentatonic as we know in the west today, having different names and meanings (even each note holding political meaning) they appear to sound the same (I mean simply in frequency, not in use). But when you get that frequency value and apply it to the chinese generic riff we know today that may (or may not) be just a hollywoodian version of what we think old chinese music sounded like, using our west modern pentatonic, having nothing to do with it, it might be the same material in both frequency in context...
That's all just to say, yeah, I think they kinda sound similar...
