Yes, I believe that strategic-management concepts and techniques benefit foreign businesses as much as domestic firms.
Because according to research the organizations which uses strategic-management concepts are more profitable and successful than those who did not use that. And businesses which uses strategic-management concepts have more improvement in sales, more profit, and more productivity as compared to firms who did not use these concepts.
Strategic management offers many other real benefits like better awareness of external threats, better understanding of strategies of competitors, an understanding of performance to reward relationships etc.
