The voice over at 10 minutes says 'Kites such as this represent Siamese men. Nowhere else in the world are kite flyers such skilled manipulators. Competing with the male kites are frivolous and wriggling female kites'
If we take into account that kite flying in Thai is a metaphor for having a tug I think this promotional video has a lot more subtext than would otherwise be evident.
There's lots of guff in this propaganda film, such as a claim that Thais eat one pound of rice a day. That's not the case even if they are referring to cooked rice and completely impossible if referring to dry rice.
However there are some nice clips of old Bangkok, and it's worth a watch for the enthusiast. There's a nice opening scene of the view from Pratumnak Hill overlooking the crescent bay of Pattaya.
To the south is Jomtien Beach but that isn't shown.
