As the Guest Country of Honor at this expo, Saudi Arabia sent a delegation of over 150 economic and trade representatives to attend and exhibit. They concluded 15 cooperation projects, worth a total of 12.4 billion yuan.

This year's expo featured trade fairs and forums on trade and investment, modern agriculture, cross-border trade, cultural tourism, health, water resources utilization, and meteorological cooperation.

First held in 2013, the China-Arab States Expo has become an important platform for China and Arab states to promote pragmatic cooperation and advance high-quality Belt and Road cooperation.

China is now the Arab states' largest trading partner. China-Arab trade volume almost doubled from the 2012 level to $431.4 billion last year. In the first half of this year, trade between China and the Arab states reached $199.9 billion.
