Don Coxe's lastest Basic Points (May 2007) raises some interesting issues in regards to acquisition of mining reserves.

From a libertarian perspective: if statist foreign entities e.g. Chinese Army or Saudi Wahhabi investment funds make a takeover for home-country mining reserves using fiat printed money (in this case USD), or if foreign statist entities (e.g. based in Brussels) block mining mergers between your domestic companies to allow their own foreign companies to acquire the domestic companies, should home-country authorities be allowed to scrutinise or block the acquisition on "national interest" grounds?
