BEIJING - China International Travel Service Ltd, the country's largest travel agency, said Thursday its net profits jumped 67.18 percent year-on-year to 684.9 million yuan ($108.83 million) in 2011.

The company attributed its profit surge to booming travel demand and the launch of new travel routes, which have catered to a greater variety of consumers.

Despite a gloomy global economic outlook, the company said it will increase its rate of expansion in overseas markets, adding that it expects fiercer competition among domestic travel agencies this year.

The company's shares dipped 3 percent to 28.14 yuan as of 1:30 pm Thursday.
