How long did it take for chopsticks to spread around the world?

Chopsticks originated in China over 3,000 years ago and gradually spread to other East Asian countries, such as Japan, Korea, and Vietnam, over several centuries. Their global spread to the Western world began in the 20th century, particularly after World War II, as interest in Asian cuisine grew. Today, chopsticks are widely used not only in Asia but also in many Western countries, reflecting the global appreciation for diverse culinary traditions.
