China Eastern Airlines Co. Ltd. on April 6 signed a strategic cooperation agreement with China Airlines, a premier airline from Taiwan, to extensively cooperate on cargo flights, passenger flights, logistics, aircraft maintenance and marketing.

Under the deal, the two carriers will extend their cooperation in some key areas such as code sharing, said Liu Shaoyong, Chairman of China Eastern.

"That means, when passengers take flights of China Eastern, they will also be receiving services from China Airlines," Liu added.

In addition, their cooperation will also boost the service quality of flights across the Straits during the World Expo in Shanghai, Liu said.
