The term Chinese wall is used mainly in the business world and uses the Great Wall of China as a metaphor for an information barrier. The Investopedia offers this explanation:

A Chinese wall is the ethical barrier between different divisions of a financial (or other) institution to avoid conflict of interest. A Chinese Wall is said to exist, for example, between the corporate-advisory area and the brokering department of a financial services firm to separate those giving corporate advice on takeovers from those advising clients about buying shares. The "wall" is thrown up to prevent leaks of corporate inside information, which could influence the advice given to clients making investments, and allow staff to take advantage of facts that are not yet known to the general public.

Wikipedia adds that the term goes back to the stock market crash of 1929. The U.S. government saw the need to maintain a separation (or an information barrier) between investment bankers and brokerage firms to limit the conflict of interest between the two.
