Costa owner Whitbread plans to expand the coffee chain in China from 344 to 900 coffee shops by 2020.
Over the last year, 43 new Costa coffee shops opened in China's biggest cities.
"China, where we operate through two joint ventures, remains an exciting opportunity", said Whitbread in its full-year financial results statement.
Strong sales at Costa overall helped to bolster Whitbread's earnings, with annual pre-tax profit rising 18.5% to £488m.
