Official numbers from Beijing show that the Chinese economy expanded by 6.7% last year - that is its lowest rate of annual expansion since 1990.

It is down from 6.9% growth in 2015 - and within the government's forecast of expansion between 6.5-7.0%.

The head of the National Bureau of Statics who calculated the growth rate has said that it is "authentic" and "reliable," this comes after officials admitted that growth figures had been inflated to meet targets between 2011 and 2014.

The country faces a number of challenges in 2017 - including the threat of tariffs from the Trump administration and the unwinding of the country's inflated property market.
