Help with another abc Q?

[elena]

Why foreign currency and the mark? Besides, wouldn't this lead to increase
of the tension b/n Kossovo/the rest of country instead of harmonising
things?
(Max: no revelations found in the introductory book on economics;
rather,this looks like killing them softly with hard currency from an int'l
terorist's manual)

 Kosovo's U.N. administration took two substantial steps toward cementing
the province's autonomy Friday, declaring the German mark its currency of
choice and starting up a customs service. Both moves distance Kosovo from
the Yugoslav state, of which it officially remains a part.

The Yugoslav currency, the dinar, remains legal tender but using it will not
be encouraged and all revenue from
the customs service will be used in Kosovo, not transferred to Belgrade.

But administration chief Bernard Kouchner, declaring the customs service
open at the Hani I Elezit/Djeneral
Jankovic border crossing with Macedonia, insisted he was not taking Kosovo
down the path to independence.
