Answer and Explanation:
The author shows how American companies have a strong influence on the economy of Singapore, as in other countries and that because of this influence, the American government can impose that not only Singapore, but that all countries have better attitudes, otherwise these companies can be withdrawn from these countries, which would cause certain economic problems.
In other words, the author states that the USA cannot impose American values in foreign territories, but it can cause these values to be met using the influence it has economically in those territories, through the list of American companies that the foreign country has.
