China's economic growth now at lowest level in 25 years

China's economic growth edged down to 6.8% in the final quarter of 2015 as trade and consumer spending weakened, dragging full-year growth to its lowest in 25 years.

Growth has fallen steadily over the past five years as the ruling Communist Party tries to steer away from a worn-out model based on investment and trade toward self-sustaining growth driven by domestic consumption and services.
