"The role of Sichuan and Chongqing as a driving force of the high-quality development in the western region is becoming increasingly evident," said Zuo Yongxiang, vice-governor of Sichuan province, at the fair's opening ceremony.

Last year, the economic scale of the Chengdu-Chongqing Economic Circle reached 8.19 trillion yuan, contributing 6.5 percent of the national economy with only 2 percent of the country's land area. The area has established three national advanced manufacturing clusters and four national strategic emerging industry clusters.

Zuo noted that the total scale of the electronic information manufacturing industry in the area has exceeded 1.6 trillion yuan and will become a world-class cluster.

As the guest country of honor at the fair, Belarus highlighted the Great Stone Industrial Park at its pavilion. Located in the capital city of Minsk, it is the largest industrial park established by China overseas.

"At this WCIFIT event, we are going to showcase the cooperation potential of Belarus across various fields to the fullest extent," said Alexander Turchin, chairman of the executive committee, Minsk Region of Belarus, while delivering a speech.
