Anon wondered recently thus:
Why did muh chinee "conglomerate" purchase the Chase Bank flagship (and beautiful) 1 Chase Manhattan Plaza bldg in downtown Manhattan back in the day (2013).
quote FOSUN Group’s New York office has been established since 2010 and located at the landmark 28 Liberty building in downtown Manhattan nearby Wall Street Financial district （formerly One Chase Manhattan Plaza acquired by FOSUN in 2013) close quote
The building is adjacent to the Federal Reserve Bank of New York, the famed "vault" that's supposed to hold lots of gold, in addition to being, well, the FRBNY.
It is known that there is a network of tunnels from 1 CMP all way up to, at least, Grand Central Station on 42nd Street. One can't blame an anon for surmising that 1CMP is connected to its next door neighbor, the FRBNY, as well.
