Concerted efforts should be made to build up a common market for common prosperity across the Taiwan Straits, said visiting Chairman James CY Soong of the People First Party in Taiwan here Wednesday.

Soong made the remarks in his speech to students and teachers of the prestigious Qinghua University Wednesday.

"Several days ago when I visited Nanjing, an old local man came to me after passing the tight police defense, saying that 'Mr. Soong, we need no warfare'. That demonstrated people across the Straits voiced the common aspiration for peace," said Soong in his speech.

Efforts should be made for making mainland and Taiwan "workshop of the world and market for the prosperity of our world," he said.

A stable, open, progressive and peaceful China is in the common interest of the world, he stressed.
