The Chinese owners of 28 Liberty are putting it on the block for an expected revaluation at $1.6 billion.

The company, Fosun, has hired CBRE to market the 2.2 million-square-foot building, Real Estate Alert reported.

But Fosun is merely seeking a strategic partner, The Post has learned, and expects to retain a majority stake in the property that was previously refinanced for $1.3 billion.

Fosun bought the former One Chase Manhattan Plaza from JPMorgan Chase in 2013 for $725 million, also through CBRE.

With JLL as agent, it has since brought in Danny Meyer’s restaurants for the top and numerous other tenants to fill the offices being vacated by the bank. It also obtained Landmarks approvals to rework the formerly barren public plaza and bring in an Alamo Draft House. However, there are still 200,000 square feet to lease.
