The China Motor Bus Company, Limited, often abbreviated as CMB, is a property developer in Hong Kong. Before its franchise lapsed in 1998, it was the first motor bus operator in Hong Kong, and was responsible for the introduction of double-decker buses to Hong Kong Island.

The MCW Metrobus is a two and three-axle double-decker bus manufactured by Metro Cammell Weymann (MCW) between 1977 and 1989, with over 4,000 built. The original MkI was superseded by the MkII which had a symmetrical windscreen with an arched top in 1981, although production of the original MkI continued for the Greater Manchester Passenger Transport Executive and London Regional Transport until 1983 and 1985 respectively. The Metrobus was conceived as an integral product manufactured completely by MCW, but Alexander and Northern Counties also bodied some examples.
