Chopsticks originated in ancient China as early as the Shang dynasty (1766-1122 BCE). The earliest evidence of a pair of chopsticks made out of bronze was excavated from the Ruins of Yin near Anyang, Henan, dated roughly 1200 BCE.
While China, Japan, Korea and Vietnam had long included chopsticks as part of their traditional eating utensils, the use of chopsticks in a limited sense spread to other Asian countries in recent centuries with the influx of Chinese immigrants in Southeast Asia.
Many countries in Southeast Asia had traditionally eaten with their hands, but through the influence of Chinese immigrants, countries such as Thailand began to use chopsticks.
