The Indian train system, built by the British, is vast and reaches many more towns than China's.  Compare this to China's train system which only recently reached Lhasa.  Combine this with cultural differences and the fact that China's economy, based on manufacturing and cheap labor, and you have a situation where urban migration happens on a larger scale in China than it does in India.  Of course it's large in India as well, but the system is 'working' relatively well in China: migrants come from villages to towns, work all year, then go home during Spring Festival to share their earnings with their family.  The ones that get used to this, or for other reasons, make a permanent move to the city.  Chinese cities seem to be swelling much faster than India's, and the Chinese government is building the infrastructure to support it.  The vast, sprawling slums that exist in Indian cities don't seem to be allowed/visible in Chinese cities - perhaps those people are not allowed to settle down in the city in the first place.

I was speaking with a professor at Xinjiang University in Urumqi, part of the 'Wild West' of China.  He was talking about a project they are planning to do with mobile phones.  I did a bit of brainstorming and wanted to hear his feedback on an idea I had for rural citizens of Xinjiang who don't have mobile phones.  He looked at me like he didn't understand: everybody has mobile phones in Xinjiang.  I have a hunch that even this man hasn't been 'out there' to see if Grameen Phone's system would/does work in rural Xinjiang, and even HE is assuming that everybody has phones 'out there'.
