Bank of China Group (中銀集團; BOCG) was the brand used to denote 13 banks that were almost entirely owned by the Chinese government that operated in Hong Kong, until their merger in 2001 to form Bank of China (Hong Kong).
The exception was the Hong Kong branch of the Bank of Communications, which left BOCG in 1998.
The BOCG brand is still retained by the life insurance and casualty insurance operations of the Bank of China, in both Hong Kong and Mainland China.
As all of the new capital were from the Chinese government, private ownership in the public-private banks were substantially reduced to less than 1%.
Treasury and foreign currency exchange operations were also centralised.
