Well, there certainly may be other motivations at play, but it's also easier to keep foreign grants secret. The NIH, NSF, and American Cancer Society all make their awards public and searchable (I assume it's true for any organization with serious money or federal funding but those are the only ones I have come across). That said I also don't know if the federal funding agencies actually check outside of their own organization whether someone failed to mention a grant on an application.
