Chinese President Hu Jintao arrives in US for state visit

Chinese President Hu Jintao has landed in the US for a four-day state visit, in a crucial meeting of the world's two biggest powers.

He was greeted by US Vice President Joe Biden for what is likely to be Mr Hu's last state visit to the US before a handover of power is completed in China in 2013.

US President Barack Obama will host a private dinner on Tuesday for Mr Hu at the White House.
