has 30% fewer total prisoners?

Supposed that the number of total prisoners in the United States is A, the number of total prisoners in China would be equal to 70% of the A?

Context:

The US, "the land of the free," has the biggest prison population in the world and the highest rate of prisoners per capita of all countries – including countries that President Bush believes need liberating by US armed forces.

Even China, with one party rule and a population that is 4.5 times larger than the US population, has 30% fewer total prisoners than the US. China’s per capita rate is a small fraction of the US rate.
