Experts say enhanced efforts can optimize economy

Experts on Monday called for enhanced efforts to revitalize free trade and optimize the investment environment to inject sustained energy into the world economy.

The ongoing China International Import Expo, or CIIE, they said, is a powerful tool for trade facilitation and will create fresh momentum.

Yousef Abdullah Al-Benyan, vice-chairman and CEO of Saudi Basic Industries Corp, said in a forum discussion that free trade is "crucial" not only for the company's success but also for the world economy.
