Detained journalist Gao Yu on China's challenges

For two weeks, Gao Yu's friends and family tried to find out what happened to the 70-year-old writer and commentator after she disappeared into police custody.

And now they know: she has been accused of leaking state secrets - a serious charge that could result in a lengthy prison term.

The BBC Beijing Bureau interviewed Gao Yu in March 2013 to hear her thoughts on the challenges facing Xi Jinping as he assumed his position as China's President.

She also spoke about the economy, Chinese politics and many of the country's social challenges.

Here is an excerpt of that interview.
