EU calls for unity from Americas

From BBC News:

European leaders have expressed concern at the mixed signals coming from Latin America, as tensions over energy overshadow a summit in Austria. Bolivia's nationalisation of its gas sector and a planned new Venezuelan tax on oil firms have dominated the agenda. But with some Latin American and Caribbean nations keen to expand trade, the European Commission president urged the nations to present a common vision.
Growing differences between them may prevent a trade deal, analysts say. Some American countries, like Chile and Colombia, favour free market economics and are keen to attract investment from Europe, says the BBC's Latin American correspondent Steve Kingstone. But others, led by Venezuela and Bolivia, are moving towards greater state control of their economies. Images of troops occupying European-run gas installations in Bolivia have made the EU wary, he adds.
The tensions between the two blocs have surfaced at the summit, with Mexican President Vicente Fox warning counterparts that governing by populism "hinders meeting the challenges we have".
