Marriott International is becoming more, well, international.

The Bethesda-based hospitality giant on Tuesday announced plans to buy Canadian company Delta Hotels and Resorts for roughly $135 million.

The deal would add 38 hotels and 10,000 rooms throughout Canada, making Marriott the largest full-service hotel company in that country and further expanding its global reach.

“Delta has an impressive portfolio of hotels that are among the most preferred in Canada,” Arne Sorenson, president and chief executive of Marriott, said in a statement. “With this acquisition, we are continuing our focus on. . . growing in attractive regions outside the U.S.”

Marriott has undergone a rapid international expansion in recent years. Last week, the company announced that it expects to have a 1 million rooms open or in development this year as it ramps up its presence in Asia, the Middle East and Africa.

In 2014, Marriott signed agreements for more than 650 new hotels — or nearly two new hotels a day. Major deals included a $186 million purchase of Capetown-based Protea Hospitality Holdings, which nearly doubled Marriott’s presence in Africa. The company also debuted Moxy Hotels, a line of boutique properties aimed at millennial travelers in Milan, with plans to expand to Berlin, London and Munich in the coming months.

Marriott’s latest acquisition, which is awaiting third-party and governmental approval, would increase the company’s presence in Canada by nearly 60 percent to 120 hotels and 27,000 rooms. The deal is slated to close in the second quarter of this year.

Marriott oversees 4,100 properties in 79 countries. Last year, the company posted annual revenue of $12.8 billion.
