The Hong Kong and China Gas Co Ltd says there has been a small growth in its industrial gas business this year, despite a stagnant performance from its residential gas operations.

Its net profit rose 11 per cent last year to 5.86bn HKD ($750m) from the year-earlier 5.28bn HKD ($676m), benefiting from revaluation of investment properties and sale of some real estate assets.

It said growth of its gas business and property rental income slowed in the period with profits from the segment reaching 3.22bn HKD ($412m), barely changed from a year earlier.
