The title partnership has been agreed for a ten-year period ending in 2029.
Furthermore, Wanda Sports Group will work closely with World Athletics to create a new annual event.
Further areas of co-operation are the development of youth athletics in China.
The rebranding also sees the Diamond League assume a brand new logo.
With its three forward-facing contours, the new logo reflects a leap into the future for athletics' biggest global series. The lines also serve to divide the logo into three sections, representing the three areas of athletics: run, jump and throw.
The overall aesthetic is a strong contemporary mark which exists in the modern world but is timeless in its simplicity.
