Several countries have enacted so-called "blocking legislation". Blocking legislation mandates the confidentiality of information and documents and attempts to block foreign efforts to obtain evidence from residents of the enacting jurisdiction. It is often enacted by countries seeking to foster banking and financial industries, such as Switzerland, the Bahamas, Panama and Vanuatu. It generally prohibits residents of those countries and corporations doing business there disclosing confidential business information about others doing business there.
