The World Economic Forum (WEF) in the Chinese city of Dalian this week for the so-called Summer Davos comes at a time when China is assuming a greater global profile. [...] This week’s forum is not the first time this year that China has used the WEF to position itself positively on the world stage.

Chinese President Xi Jinping has delivered a keynote speech at the opening ceremony of the Boao Forum for Asia 2013 in the coastal town of Boao, in China's Hainan Province. President Xi expressed his wish to work with regional leaders to build a better future for Asia and the world.

China is earnestly striving to become a respected world power, one that finally surpasses the United States. The day could come when its economy, even its military, is larger than America's.

Kennedy School of Government at Harvard University on these topics.
