Somewhat unrelated to this specific case, but what happens to all that money? The government can't exactly budget for influxes of cash like this, so what do they do with it and who gets to spend it?
Government money/budgets isn't that precise, income from taxes are variable, for example. Also most countries spend more then they make anyway (deficit).
It's accounted for as revenue via fines and spent according to the normal budget.
The exception to what I said in the other post is sometimes lower branches of government hold on to their cash for various purposes and spend it however the lower branch wants to essentially.
Seriously? A billion dollar "windfall" for the government of a country with one the world's largest economies is basically just pissing into the wind. China's government spends $2.3 trillion in a year, so this is a fraction of a tenth of a percent of their spending.
