Ayumi Kusaba from the Beijing office of the Japan External Trade Organization arranged for 12 Japanese food companies to participate in the exhibition. He called the expo "an opportunity for enterprises from all over the world to communicate and showcase their products."

"I have participated in all seven consecutive expos," he said. "We are very optimistic about the Chinese market. Through this platform, we hope to introduce our products to more Chinese consumers, especially those from the central and western regions."

The expo also provides a chance for local companies to expand their businesses overseas and attract foreign investors.

Shaanxi Construction Engineering Holding Group Corp is the first construction enterprise in Shaanxi to go abroad with China's reform and opening-up. The group's overseas business unit, Top International Engineering Corp, continues to accelerate its development.

As of the end of October, it completed contracts valued at 14.6 billion yuan ($2 billion). Its annual growth rate is expected to exceed 20 percent.

Yan Yongjun, president of Top International, said the company has set up territorial operations in 32 countries and regions, building six overseas business regions — Western and Southern Africa, the Middle East, West Asia, Central and South Asia, Southeast Asia and the South Pacific.

In the first three quarters, Shaanxi's total import and export volume to countries involved in the Belt and Road Initiative increased by 22.8 percent year-on-year, and its total export volume to five Central Asian countries increased by 205.2 percent year-on-year.
