Marriott International Inc. (MAR - Get Report) knows the possibility of a trade war represents a challenge for American business. That's why finance chief Leeny Oberg told TheStreet that the company insists "keeping an eye on that is important."

Oberg said Marriott's major expansion overseas in recent years isn't slowing down anytime soon. While about 65% of Marriott's business is in North America traditionally, more than half its pipeline of rooms and projects to come are international right now.

But as President Donald Trump weighs tariffs that many worry could stoke a trade war, Marriott could face a new challenge in the lodging industry. "At the end of the day, our business is driven by GDP growth," Oberg said, "GDP growth in the markets where our hotels are."

If a trade war slowed the economy, Marriott could feel the backlash as consumers spend less and save more. But for the time being, Oberg said it's "too soon to tell" if a trade war could actually come to fruition.
