Angry Birds opens online store

Rovio Entertainment Ltd, the maker of the popular game Angry Birds, on Thursday officially opened its virtual store on Tmall.com, China's biggest e-commerce website where companies sell to customers.

The hit game developer is attempting to further cash in on the Chinese market by selling authentic Angry Birds products as most of the Angry Birds spinoffs currently available in China are counterfeits.

Its online store provides spinoffs ranging from T-shirts to food, including Angry Birds cookies targeted at the coming Valentine's Day.

Last October, the Finnish company opened its operation in Shanghai, its first overseas branch outside Finland.
