China and the US have had a largely symbiotic relationship since the1980s regarding labor, manufacturing, and technology. In the early 1980s, thegovernments of the two countries agreed that US corporations could contractwith Chinese organizations to move their manufacturing operations to China toutilize the competent work and low wages of Chinese employees. As a result,approximately one sixth of US manufacturing jobs were lost to Chinese facto-ries.
The author claims that the relationship between China and the U.S. has been "largely symbiotic," but this statement may not be logically supported by the evidence provided. A truly symbiotic relationship implies mutual benefit, yet the example focuses mainly on U.S. job losses. The argument might be valid in structure but lacks balance in demonstrating how both sides benefited. More evidence on what the U.S. gained (e.g., lower consumer prices or corporate profits) would strengthen the validity.
