Most Western countries already have instruments to deter foreigners from making unwanted investments, not only in defense industries, but also in other sectors. But, while Germany’s Foreign Trade and Payments Act protects against takeovers in the defense industry (though the law needs strengthening) elsewhere Germany has no system for examining investments by SWFs that may be strategically motivated.
大多数的西方国家都已经出台了相关的举措，不仅在国防工业，也在其他的工业部门阻止外国人进行非其所愿的投资。但是，尽管德国的《对外贸易和付款法案》保护国防工业不被并购（虽然该法律仍需强化），而在其他产业，德国却没有审查可能具有战略目的的SWFs投资的体系。
