Patricia, I am also looking for this rice. IMHO the perfect rice blend. At 120 baht ($3.70 us) per vacum packed kilo id buy this all the time if available.
I am trying to contact and see what we can do to get some of this imported. Will post results here.
I did find an importer who seems to have a similar product;
But i havent tried or obtained this yet. I really want the Golden Pheonix brand!
all my best
