Chopsticks are kitchen/eating utensils that are shaped pairs of equal-length sticks that have been used in East Asia for over four millennia.

First invented and used in China, chopsticks later spread to countries that were tributary states of the Empire of China. In Southeast Asia, only Vietnam and ethnic Chinese communities consume all food with chopsticks. In Cambodia, Laos, Myanmar, and Indian and Malay communities in Singapore and Malaysia, as well as in Nepal, chopsticks are generally used only to consume noodles. In Thailand, chopsticks have only recently started being used along with the spoon and fork. Similarly, in the US, a sizeable minority of people use chopsticks, especially for Asian meals.
