Huaihai Campaign
Starting from 1946, a significant number of US-supplied Shermans (together with American M3/M5 Stuart light tanks, received under the Lend-Lease program of WWII, as well) saw combat action with Nationalist Chinese (Kuomintang) forces against communist Chinese troops, especially during the Huaihai Campaign of the Chinese Civil War. A few Nationalist Shermans ended up being captured by communist forces as the former retreated and were forced off the mainland. After the Republic of China relocated to Taiwan in 1949, the United States supplied both M4 and M4A1 Shermans to the Nationalist Chinese military.
