Facing intense fast food competition in the U.S. and Canada, Burger King has increasingly concentrated on opening stores in overseas markets. In June, the company announced plans to open 1,000 restaurants in China by 2019.
The company has also partnered with Russian franchisees to launch hundreds of new locations across Russia in coming years.
In fact, 80% of Burger King locations opened in the past year are in the Middle East, Europe and Africa.
Burger King, which has also scrambled to add new menu items and update its restaurants, currently has 12,600 locations worldwide, less than half of the 33,000 locations of its arch-rival McDonald‘s (NYSE:MCD).
