BEIJING (Bloomberg) - China's economy last year grew slightly more slowly than the government had previously announced.

The world's second-biggest economy expanded 7.3 per cent in 2014, down from an originally announced 7.4 per cent, the nation's statistics bureau said on Monday (Sept 7).

The change comes mainly from the services industry, which grew by 7.8 per cent, revised down from 8.1 per cent.
