The mainland's economy continued to power ahead in the first half, prompting economists to project year-on-year growth of between 7.5 per cent and 7.9 per cent.
The gross domestic product growth to be announced today will again confirm China as Asia's star economy having shrugged off concerns of the economic slowdown in the United States.
It also indicates the second-quarter sustained a surprisingly strong quarter-on-quarter growth of 7.6 per cent.
Early this year, Beijing feared it could have difficulty matching last year's 7.3 per cent economic growth.
Economists said strong exports, a flood of foreign investment and robust domestic demand and continued state spending helped China outshine its neighbours in the first half.
Standard Chartered Bank senior economist Liao Qun, who forecast first-half growth of 7.7 per cent, said: 'The first-half economic growth would be stronger than most expectations.'
A strong first-half growth will help China comfortably reach this year's target of 7 per cent growth. Economists expect full-year growth will be between 7.5 per cent and 8 per cent.
