Fears about national security are greatly overblown, and are often simply an attempt to justify protectionist measures. Very few companies pose a national security risk, and those that do are covered by existing regulations – so that, for example, the USA could veto Dubai Port World’s bid to take over American ports. Most SWFs do not seek full control of companies they invest in, so they are not in a position to manipulate their assets for political gain, even if they wished to. [1] In reality, countries set up SWFs for economic reasons and they represent a major national investment, the value of which would be expensively destroyed if they once tried to abuse their position. Nor are there any actual examples of a country trying to exert political influence through its sovereign wealth fund. Overall, tying a wide variety of states into the international economic and financial system is beneficial, as it gives them a stake in the peace which the global economy needs for prosperity and so makes them less likely to pursue aggressive foreign policies. Conversely, alienating the governments of other states by designating them as dangerous predators who cannot be allowed to invest in our companies is a sure way to create enemies.
