A growing number of scientists and engineers who have worked abroad are seeking business opportunities in China after encountering career barriers overseas.

More than 200 overseas Chinese and representatives of 30 associations for Chinese abroad attended the two-day Conference on China International Exchange of Professionals at the Shenzhen Convention and Exhibition Center, which ended on Thursday.

Some of them, who still had luggage with them, rushed to the venue in the morning eager to discuss project proposals with potential investors and partners.
