I-Fei Chang has resigned from the Chinese company building the $1-billion Metropolis project downtown, the Los Angeles Times reports.

The U.S. arm of Shanghai-based Greenland Group said Chang departed as the subsidiary’s chief executive for “personal reasons,” the newspaper says. Gang Hu, a former executive vice president and a founding member of the company’s U.S. subsidiary, Greenland USA, will replace Chang, according to the Los Angeles Times.

The Metropolis mega-project is projected to include condominiums, hotel rooms and shopping retail in South Park.
