The biggest challenge facing Chinese cities is handling the massive, ongoing influx of rural residents, according to a top expert on urban management.

"It's a challenge for almost every country, but it's a big one for countries such as China and India because of their large populations," said Alain Le Saux, secretary-general of the World Association of Major Metropolises.

Speaking at the Board of Directors meeting, held in Guangzhou from Nov 14 to 17, he said that in a global financial crisis, it is difficult for city leaders to allocate sufficient funding for new settlements, transportation, job opportunities and other resources to satisfy the needs of a growing population.
