China's economy to overtake US in next 4 years

China will overtake the US in the next four years to become the largest economy in the world, says a leading international thinktank.

The Paris-based Organisation for Economic Co-operation and Development (OECD) said China's economy will be larger than the combined economies of the eurozone countries by the end of this year, and will overtake the US by the end of 2016.

Global GDP will grow by 3% a year over the next 50 years, it says, but there will be large variations between countries and regions. By 2025, it says the combined GDP of China and India will be bigger than that of France, Germany, Italy, Japan, UK, US and Canada put together.
