China has approximately 1.45×10^9 people, while India has approximately 1,400,000,000 people. To find out how many more people live in China than in India, we subtract the population of India from the population of China:

1.45×10^9 - 1,400,000,000 = 5×10^7

Therefore, there are 5×10^7 more people living in China than in India.
