Hangzhou Bay Sunac Tourism City (Previously known as Six Flags Zhejiang) is a partially completed theme park and entertainment complex in Jiaxing, Zhejiang, China, about 45 miles from downtown Shanghai. It was announced by the Six Flags Entertainment Corporation in 2015 as part of the company's bid to open multiple parks in China. In February 2020, Six Flags dropped out of the project when their partner, Riverside Investment Group, encountered was unable to meet their financial obligations. In June 2020, Sunac China Holdings took over the project and opened the Sunac Water Park in June 2021. The complex was projected to open in stages, although nothing else has since made progress.
