Shanghai is working to restore its image as the Paris of the Orient in order to attract luxury travelers. China's largest city is preparing for next year's World Expo by transforming itself into a metropolis filled with landscaped parks, quiet alleyways and shiny new skyscrapers. The Peace Hotel is undergoing a complete overhaul, one of many projects meant to attract affluent travelers. "The barrier is just being pushed higher and higher," said Rupert Hoogewerf, a researcher of wealthy Chinese. "Previously, (the hotels) may have sought to be the best in the city. Now they're aiming to be the best in the country, or the world."
