Moody's Investors Service has placed China Mobile under review for a possible upgrade due to its stronger financial profile.

The credit ratings agency yesterday said China Mobile, the world's largest mobile carrier with 160 million users, had demonstrated its ability to manage growth - both organic and through acquisitions - leading to a more sustainable business.

'This places China Mobile in a very strong competitive position, which is unlikely to erode over the medium term,' Moody's said.
