I think he refers to Gelephu Mindfulness City. I read it differently, not as a generic globalist city but very much a middle ground between Bhutanese culture (deep Buddhist presence, it will maintain vernacular architectures codes throughout, no skyscrapers) and global capital attractiveness (special economic zone, some tax benefits but not a tax haven in any way, crypto adoption, etc.)
Bhutan sovereignty is guaranteed by the fact that China (Tibet) also shares a border with Bhutan. It's a neutral place between the two powers. Although its ties are much closer to India (geographically, the flattest part is on its southern border with India--the location where Gelephu Mindfulness City will be located).
It's because of that youth exodus (to Australia mainly) that the government is pushing for Gelephu Mindfulness City as place for innovation and new business opps. That's what the gov't officials directly argued when asked.
