The Associated Chinese Chambers of Commerce of British Malaya Established in 1921.
The First Conference of ACCCBM was held on 2nd July 1921 at the Selangor Chinese Chamber of Commerce, No. 167, Petaling Street, Kuala Lumpur. The Chairman as well as the coordinator of the First Conference was Mr. Lim Eu Toh, then the President of the Penang Chinese Chamber of Commerce. The purpose of the Conference was to unite the strengths, to formulate constructive proposals and remedial measures in resolving commercial and financial stringency that encountered by Malaya at that period of time. Resolutions passed at the Conference were then embodied in a Petition on Trade Depression in Malaya and submitted to Sir Laurence Guillemard, Governor of the Straits Settlements and High Commissioner for the Federated Malay States.
The Petition was jointly submitted by nine (9) Chinese Chambers of Commerce, i.e. from Singapore (represented by Seah Lye Keat & Ong Hui Ghee), Penang (represented by Lim Eu Toh & Lee Chin Ho), Malacca (represented by Sim Hong Pek & Tan Swi Chan), Selangor (represented by Yap Loong Hin & Choo Kia Peng), Perak (represented by Leong Sin Nam & Samuel Fung), Batu Pahat (represented by Ying Poh Sung & Tan Toh Chong), Kuala Pilah (represented by Yeap Choo Nyah & Lim Kong Thong), Bentong and Kuantan (support by written confirmation). These nine chambers were the founder members of the ACCCBM.
Protecting Interest & Promoting Favourable Business Environment for the Benefits of Merchants & Community.
The initiation of ACCCBM marked the long and winding journey of the ACCCIM in protecting the interest and promoting a favourable business environment for the Chinese merchants and businesses.
During the early days of the establishment of ACCCBM, Malaya was confronted with trade depression and commercial and financial stringency. The world rubber supplies surpassed its demands. In response to the overstocking rubber market, the British Colonial Government imposed restrictions and limitations on export of rubber to stabilize low rubber prices resulting from a glut of rubber in 1922. Even though rubber prices stabilized to some extent, ACCCBM was of the view that in the long run, it would not be benefited the industry and the entire business in Malaya. In this connection, a Petition was submitted to the British Secretary of State for the Colonies in 1925 to call for immediate removal of rubber restriction. 
In 1932, the British Colonial Government ignored the opposition of Chinese representatives in the Legislative Council led by Tan Cheng Lock and passed the Aliens Bill that regulate the immigration of Aliens into the Colony and to control their residence therein. ACCCBM submitted a Memorandum to Sir Samuel Wilson on “widespread uneasiness” of the Chinese community in Malaya at the discrimination policy of the Government so as to protect the interests of the Chinese community.
According to various records and reports pertaining to ACCCBM between 1921-1940, besides Government economic policies, ACCCBM also often voice up for the interests of the Chinese merchants and expressed its views on various issues concerning the interests of the Chinese community, including the prohibition of opium smoking, abolition of brothels, to add Chinese characters on road signs and at the printing of Government bills and notices, etc.  With the expressive voice often heard and much attention gained from the political and economic arena, the British Colonial Government would expedite its response and this indeed had made ACCCBM the most influential organization representing the Chinese merchants and Chinese community in general. 
Collective Wisdom & Efforts, Compete for Success
In the 1930s, with more effective coordination between Chinese representatives in the Legislative Council such as Tan Cheng Lock and Chinese Chambers of Commerce, a strong united force was gradually formed. Many political and economic leaders became the central pillar of strengths for ACCCBM. The views and recommendations of the ACCCBM that reflected the voice of the Chinese merchants and Chinese community were more effectively heard and taken into consideration by Government decision-making bodies. 
With the rise of the influence of the ACCCBM, its Constituent Chambers had worked closely with the parent organization so as to response timely to policies changes, protecting the interests of Chinese merchants and smooth dissemination of information.
ACCCBM not only served as a platform for local Chinese merchants, it began to receive international recognition. For example, the China Government and many business-related organizations of various provinces began to work with ACCCBM as a communication platform to gather and disseminate information.
During the Japanese invasion into China, ACCCBM led the various organizations in Malaya to support the relief work. However, when the British Colonial Government imposed income tax to fund its war in Europe, ACCCBM and various organizations in the Malaya had expressed their disapproval and submitted a Joint Memorandum to the British Colonial Government. This was one of the major incidents before Malaya occupied by the Japanese. 

ACCCIM Reinstated After War & Continued Its Mission  
Many restorations work need to be done after Second World War. On 23rd February 1947, business elites from 13 Chinese Chambers across 11 states had its inaugural Conference in Kuala Lumpur and reinstated The Associated Chinese Chambers of Commerce of Malaya.
Compared with the name adopted before Second World War, only the word “British” was omitted.
Resolutions pertaining to the welfares of the regional Chinese community and merchants were passed during the reinstated conference of the Associated Chinese Chambers of Commerce of Malaya. At the Conference, it also decided to submit a letter to the British Secretary of State for the Colonies to reject the new constitutional proposals which was unfair and undemocratic, particularly unfavorable in obtaining citizenship for the Chinese which hinder unity in Malaya.  Singapore was also not included in the Federation which was not conducive to the administration and economics for the Federation.
After reinstatement, membership of The Associated Chinese Chambers of Commerce of Malaya expanded into a model with Constituent Chambers in all states.  In 1963, the name was changed to The Associated Chinese Chambers of Commerce of Malaysia, and then to The Associated Chinese Chambers of Commerce and Industry of Malaysia (ACCCIM) in 1975. It has been known as ACCCIM since then, and is widely recognized locally and internationally. ACCCIM has 17 Constituent Chambers located separately in the 13 states of the nation, and are working closely together to further enhance the image and brand name of the ACCCIM as well as to provide the best services to the business community.
