"Regarding mining concessions, he said that the Venezuelan government should revoke the ones that are being used by international companies to profit in foreign exchanges without actually producing in Venezuela. "
I don't think that the Venezuelans have ever looked at the foreign exchanges..
I can't think of a single international company with concessions in Venezuela that's showing a profit.. Having anything in Venezuela is like dragging a ball and chain around the "foreign exchanges".
Helca has finally started to go up having broken its shackles with the perenial talking but never acting government of Venezuela...
