Bank of Communications is the fifth-largest bank in mainland China. It was originally established in 1908 and was one of a handful of domestic Chinese banks that issued banknotes in modern history. Following the Chinese Communist Revolution in 1949, the mainland operation of that bank were merged into the People's Bank of China and People's Construction Bank of China under the Communist single-tier banking system, while its continuation in Taiwan eventually became part of Mega International Commercial Bank.

The Mega International Commercial Bank is the second largest bank in Taiwan by tier 1 capital and a subsidiary of Mega Financial Holding Company. It has 108 branches in Taiwan and 39 overseas units. The bank is the sole domestic US dollar/Euro settlement bank designated by the Bankers Association.
