Summits and diplomatic snubs

As a tense G20 summit gets under way in St. Petersburg, we take a look at diplomatic snubs (or perceived snubs) at recent summits. Hu Jintao kept Nicolas Sarkozy waiting in Cannes at the G20 in 2011. A NATO summit saw Angela Merkel snubbed by Silvio Berlusconi on the red carpet. Bush Jr. and Yeltsin also make an appearance.
