List of countries and territories where Chinese is an official language

The following is a list of countries and territories where Chinese is an official language. While those countries or territories that designate any variety of Chinese as an official language, as the term "Chinese" is considered a group of related language varieties rather than a homogeneous language, of which many are not mutually intelligible, in the context of the spoken language such designations are usually understood as one standard form of Chinese variety, namely Cantonese and Standard Mandarin.^[1] In the context of the written language, written modern standard Chinese is usually understood to be the official standard, though different territories use different standard scripts, namely traditional characters and simplified characters.

Today, Chinese has an official language status in two countries and three territories. In China, it is the sole official language as Standard Chinese, while in Singapore (as Mandarin) it is one of the four official languages. It is the sole official language as Standard Chinese in Taiwan, while in Hong Kong and Macau it is co-official as Cantonese, alongside English and Portuguese respectively. Chinese is also an official language in the Shanghai Cooperation Organisation, and also one of the six official languages of the United Nations. Chinese was added as an official language in the United Nations in 1973, when the General Assembly made Chinese a working language.^[2][3]
