Revenue from China's express deliveries hit record high of 6.18 billion yuan (950.7 million U.S. dollars) in March, bringing the first quarter revenue to 15.66 billion yuan thanks to the on-line business boom during the holiday season, figures released by the State Post Bureau show.

Revenue of express deliveries from January to March last year was 12.4 billion yuan, figures show.

Domestic express delivery service experienced "a robust growth" in the first quarter as sales on various on-line trading platforms surged during and after the New Year and the Chinese Lunar New Year holiday, the bureau said.

Income of major express delivery firms grew 36.8 percent year-on-year in the first quarter, with the business volume up 53.1 percent, the figures show. Domestic intra-city deliveries shot up about 55 percent from a year earlier in term of either trade volume or revenue.
