Central power, and DRC revenue collection and allocation

There's a report on Radio Okapi stating that the DRC central government is to give one million United States dollars per month to Katanga province.  Katanga is a centre of the mining industry, and the regional finance minister wants to receive five million dollars instead, claiming that Katanga generates 11 million in revenue.

I wrote about the possible allocations of money between Katanga and the central government last month.  If we take the regional finance minister's figures on revenue generation as true, then the central government seems to be showing most of the power in the relation between the two.  In recent years, the government has been politically and militarily weak in the east of the country, so there is a contrast between the implied power in the allocation and the actual power manifested in the past.
