Chinese Premier Li Keqiang started an Africa tour on Sunday with his arrival in Ethiopia, where he will also visit the headquarters of the African Union (AU). Ethiopia is the first leg of Li's ongoing four-nation Africa tour, his first to the "Land of Hope" since he took office last year and the latest stroke of the frequent high-level diplomacy between the Asian giant and the promising continent.

As Friday's curtain came down on this year's Boao Forum for Asia (BFA), a public diplomacy event, the lasting effect on China should be progress and reform. It is fair to say that the four days of the conference, covering sixty topics and attracting over 3,000 global figures from all walks of life, were a good example of public diplomacy itself.
