The magazine "Nylon" explicitly covers this scene with articles about the two cities.
The dominance of these twin cities was acknowledged by Christine Lagarde who, as French finance minister, wanted Paris to become a similar international financial centre. Other cities which are becoming city-states in the same class include Dubai and Shanghai.
