Yeah - this is a smallish piece of land being "gifted" by China to Macau.
It is the old "no mans land", that is just over a small river that runs between Macau main Island and Zhuhai.
My understanding is that the
main focus of the development is a new campus for Macau University (large expansion of their present small campus, which is limited at the moment, due to the land size of their present site).
At least is what was told in a meeting had in Macau when assisting my friend in construction with proposals for the New University.
Although there is also some plans for some sort of smallish residential development as well, as I understand (Note: Gaming / casino's will remain limited to the other land areas in Macau which have already been allocated i.e. not be within this new district).
Be interesting to see what hits are like for this IDN later
