<P> In the United States, chambers do not operate in the same manner as the Better Business Bureau in that, while the BBB has the authority to bind its members under a formal operation doctrine (and, thus, can remove them if complaints arise regarding their services), the local chamber membership is either voluntary or required by law . In addition, Chambers represent the interests of businesses, while the BBB represents both the interests of businesses and the general public . Some Chambers are partially funded by local government, others are non-profit, and some are a combination of the two . Chambers of commerce also can include economic development corporations or groups (though the latter can sometimes be a formal branch of a local government, the groups work together and may in some cases share office facilities) as well as tourism and visitor bureaus . </P> <P> Some chambers have joined state, national (such as the United States Chamber of Commerce and the British Chambers of Commerce) and even international bodies (such as Eurochambres, the International Chamber of Commerce (ICC), Worldchambers). Currently, there are about 13,000 chambers registered in the official Worldchambers Network registry, and the chamber of commerce network is the largest business network globally . This network is informal, with each local chamber incorporated and operating separately, rather than as a chapter of a national or state chamber . </P> <P> Chambers of commerce in the United States can be considered community, city, regional, state, or nationwide (United States Chamber of Commerce). City Chambers work on the local level to bring the business community together to develop strong local networks, which can result in a business - to - business exchange . In most cases, city Chambers work with their local government, such as their mayor, their city council and local representatives to develop pro-business initiatives . There are also bilateral chambers of commerce that link the business environments of two countries (e.g. Romanian - American Chamber of Commerce, Moldovan--American Chamber of Commerce). </P> <P> Community chambers of commerce started in the UK and later spread to in the US, becoming city chambers of commerce as communities developed and became larger . Community chambers of commerce are smaller and most have a limits on numbers of members . </P>
