Ministry of Industry and Information Technology (MIIT) responded to Premier Li Keqiang's call to improve Internet services, saying it will urge companies to accelerate network speed and lower mobile Internet charges.

The construction of 4G network and speed enhancement will be this year's key focus, said the Ministry in a statement released on its website on Wednesday evening.

The Ministry has urged relevant enterprises to research and carry out detailed plans.

Premier Li said at a discussion about China's economy in the first quarter on Tuesday that the authorities should try to lower mobile data fees, and asked officials of relevant authorities to speed up coordination regarding the construction of telecommunications infrastructure.

When people go to a public place, they often want to know if there is free Wi-Fi, because mobile data is too expensive, Li said.
