There is some cost for governments nationalizing the assets of foreign firms

There is some cost to Venezuelan President Hugo Chavez taking the assets of firms:

NEW YORK (Reuters) - Exxon Mobil Corp has moved to freeze up to $12 billion in Venezuelan assets around the world as the U.S. company fights for payment in return for the state's takeover of a huge oil project last year.

The company said it has received court orders in Britain, the Netherlands and the Netherlands Antilles each freezing up to $12 billion in assets of Venezuela state oil firm PDVSA. An Exxon spokeswoman said the total that could be frozen worldwide was $12 billion.

Exxon also won a court order from the U.S. District Court for the Southern District of New York in December freezing more than $300 million belonging to PDVSA, as Exxon argued it would have little chance to recoup its investment from PDVSA should it win its arbitration. . . .
