The World Expo is gearing up for its 2015 installment in Milan with China the latest country signing on to participate.
Shanghai hosted the 2010 edition of the World Expo, drawing a record 72 million visitors during its six-month run, almost all of them Chinese tourists. The Chinese trade council said in a letter Friday to the Milan organizers that it hoped to contribute to the 2015 theme: "Feeding the Planet, Energy for Life."
The first Great Exhibition was held in London in 1851 to mark the coming of the Industrial Revolution; the Eiffel Tower was built for the 1889 Parisian edition.
In recent years, Expo themes have dealt with pursuing sustainable, balanced growth.
