First used by the Chinese, chopsticks later spread to other East Asian cultural sphere countries including Japan, Korea, and Vietnam. As ethnic Chinese emigrated, the use of chopsticks as eating utensils for certain ethnic food took hold in South and Southeast Asian countries such as Cambodia, India, Laos, Nepal, Myanmar, Singapore, and Thailand. In India (mainly in Himalayan region), Laos, Myanmar, Thailand, Nepal, chopsticks are generally used only to consume noodles. Similarly, chopsticks have become more accepted in connection with Asian food in Hawaii, the West Coast of North America, and cities with Overseas Asian communities all around the globe.
