Explanation:

Historically, U.S. companies, like the United Fruit Company, owned significant amounts of land in Guatemala. Guatemalan policies that threatened these land - holdings or business interests directly affected U.S. economic interests. While other factors like expatriate communities or regional influence concerns existed, the land - ownership by U.S. companies was a major point of contention.
