How does nationalization affect international business?

Nationalization Affects International Business: dramatically by causing a country (A) to cease and desist production predicated upon the notion that foreign industries/country (B) believes that they are being "economically" exploited by Another Country (A) and often times is genesis by rebels within country (B). Example: If a private company [in] country (A) drills for oil, via the purchase of leases on the land, in country (B) where the oil is domiciled and begins to make money hand over fists; although the land is privately owned, government (B) can nationalize (take over) and cease foreign production in the oil fields for the greater good of the most people in their country (B). Much like that of "Eminent Domain", in North America, only on a global scale.

Hope this helps a bit! :-)
