LONDON -- It has been a long road for former middle distance runner, Lord Sebastian Coe, who won gold medals in the Moscow and Los Angeles Olympics and has gone on to become the driving force behind the London Olympic Games. Those Games officially began with the opening ceremony in the Olympic Stadium on Friday night. "We are about to embark on the greatest sport we have ever seen and most of us will ever see in our lifetimes," said Lord Coe, who was the head of the bid which brought the Games to London.

In 2009, while I was working in public diplomacy on NATO's international staff in Brussels, I was asked to produce a promotional campaign to be posted in the Washington, D.C., Metro system for NATO's 60th-anniversary summit in Strasbourg and Kehl. In response, I asked member countries to suggest powerful images that showed Allied forces in action in Afghanistan.

The Chinese people I met while I was studying in the U.S. in the early 2000s gave me the strong impression of being aggressive in pursuing their goals. In many cases, five people shared a one-room studio to save on rent, though things might have changed now that China is the world’s second-largest economy in gross domestic product and trade.

As a young person asking the International Olympic Committee to commemorate the lives of 11 athletes massacred in Munich in 1972, I have been asked why I care to fight for the world to remember an event that has been repeatedly ignored by the IOC and, until recently, the rest of the world.

China strives to project a profile on the global stage as a responsible state because some western observers remain wary of "an assertive China" after its rapid rise to become a global economical power house.

On July 25, Department Secretary of State Bill Burns announced the creation of Networks of Diasporas in Engineering and Science, or NODES, at an event organized by the Office of the Science and Technology Advisor to the Secretary of State (STAS).

London 2012 organisers have apologised and blamed human error for Wednesday's wrong flag mix-up when South Korea's flag appeared alongside North Korea's women's football team on stadium screens as players warmed up before their opening match. The team left the pitch in protest at the blunder and initially refused to play but the game with Colombia at Hampden Park, Glasgow, eventually kicked off more than an hour late after hurried corrections to the video rectified the spectacular mistake.
