Foreign concessions refer to areas within a country where foreign powers have special rights and privileges, often established through treaties. These concessions typically allow foreign businesses to operate under their own laws rather than the local laws, leading to a unique legal and economic environment. Historically, foreign concessions were common in places like China during the late 19th and early 20th centuries, where various nations, including Britain and France, set up zones in cities like Shanghai. These areas often became centers of trade and commerce, significantly influencing local economies and cultures.
