China Resources Gas Group Ltd.'s first-half net profit fell 18%, as gas demand for industrial and commercial users declined amid the Covid-19 pandemic.

The Hong Kong-based gas supplier said Tuesday that net profit for the period fell to 2.40 billion Hong Kong dollars (US$309.7 million) from HK$2.93 billion a year ago.

Revenue fell 20% to HK$22.57 billion, as total natural-gas sales fell 5.3% to 13.25 billion cubic meters, the company said.
