You can officially call him "Mister President" now.

Xi Jinping has taken the title from Hu Jintao, completing the country's leadership transition. It comes four months after Xi became General Secretary of the Communist Party.

Political commentator and columnist Frank Ching says, "I think Xi Jinping knows that the main problems of China are domestic. When he first became the party leader back in November, he came out and met the international press. He gave a speech and said not a word about foreign policy. It was all domestic. So I think that's where the emphasis is going to be."

The question is where to start.
