"We will continue exploring overseas market opportunities and growing our games business on a global scale," Ding added.

In the second quarter, overseas games revenue accounted for more than 10 percent of the total games net revenue, according to Yang.

The company has also striven to enlarge its footprint in the broader North America games markets, particularly Canada.
