The Yangtze Service Medal is awarded for service in the Yangtze River Valley between September 3, 1926 and December 31, 1932, a period of significant unrest in the region.

The decoration may also be awarded for those military service members who served on permanent duty in Shanghai, China, provided such service was in direct support of landing operations in the Yangtze River Valley (e.g. Nanking incident of 1927).

The designer of the Yangtze Service Medal is John R. Sinnock of the Philadelphia Mint.

[2] Sinnock was the eighth Chief Engraver of the United States Mint from 1925 to 1947.
