one state is what?

Malnutrition is still, of course, a major problem in India, so it's perhaps surprising that many Indians are seriously overweight. In fact, obesity has become such a major concern there, [one state] has proposed a so-called fat tax of 14.5% on restaurants that sell fast food, to try to make people more health conscious.

One state above means the government of India? or a region of a country that is controlled by the country's central government but that has the authority to make its own laws about certain things?
