The year 2012 marked a coming of age for tiny landlocked Laos. In July Hillary Clinton became the first U.S. secretary of state since the 1950s to visit the country. The World Trade Organization formally voted in October to allow Laos into the trade grouping after years of negotiations. In early November, Laos's capital Vientiane hosted the Asia-Europe Meeting, which was attended by dozens of world leaders and senior officials, including the prime minister of China and the president of the European Council. Laos' estimated economic growth of 8.3% last year likely made it Southeast Asia's top economic performer.
