The agreement brings Wanda's commitment for IMAX cinemas in China to 360, according to an IMAX statement, in a partnership that dates back to 2007.
Owned by billionaire Wang Jianlin, Wanda is seeking to shift its focus from property to services and entertainment as profits wane in China's real estate sector.
This month Wanda announced it had bought the London-based Odeon & UCI cinema group in a deal worth around USD 1.2 billion.
IMAX, headquartered both in the United States and Canada, now has 1,102 cinemas in 69 countries, with a total of 335 already open in China.
