Chinese President Xi Jinping has stressed support for the country’s vulnerable elderly and youth in a new year address that acknowledged the strains on some of the 1.4bn-strong population. Xi’s speech comes after his economic planners have for much of the past four years struggled to restore consumer confidence or address rising youth unemployment and slow wage growth.

The Chinese leader projected confidence amid Beijing’s economic struggles and ahead of the inauguration of Donald Trump, set to take a hard line on China.
