Chinese President Hu Jintao has opened a Communist Party congress that begins a once-in-a-decade power transfer with a stark warning on corruption.
Addressing more than 2,000 delegates, Mr Hu said that a failure to tackle the issue "could prove fatal to the party".
China faced unprecedented opportunities and challenges, he said, and the nation should "aim higher and work harder".
His speech starts a week-long meeting that will see a new set of leaders unveiled. Martin Patience reports.
