China's economy grew 6.9 per cent in 2015, the slowest pace in 25 years. The growth rate, released by China's the National Bureau of Statistics (NBS) today, moderated to 6.8 per cent for the fourth quarter. It is the lowest quarterly rate since the global financial crisis in 2009. Chinese Premier Li Keqiang last year had said that the Chinese government targeted an annual economic growth of around seven per cent for 2015. As per the new data, China's Gross domestic product (GDP) reached 67.67 trillion yuan that is about 10.3 trillion dollars in 2015. Service sector accounted for 50.5 per cent, overtaking the manufacturing, the NBS said. Factory contribution to the GDP was 10 per cent lower than services as the Chinese government tried to shift from investment powered growth to innovation led expansion.Analysts said if the economy slips below 6.8 per cent the government may have to opt for a stimulus package. Chinese government enhanced investments in infrastructure to avoid stimulus package. The slowdown has already destabilised China's stock market last year which also had negative effect in the world markets. China had worst stock market crashes last year which wiped out about 3.2 trillion dollars of capital, prompting government initiate investigation.
