The event brought together 23 quality Uzbek export enterprises and 50 Xinjiang-based companies engaged in import-export, cross-border e-commerce and trade circulation, focusing on commodity trade and industrial collaboration to deepen bilateral industrial and supply chain cooperation. During the event, Uzbekistan's Mingboshi Ceramics Co., Ltd. signed a strategic cooperation agreement with Xinjiang Zhongzhi Digital Technology Co., Ltd. to jointly build a demonstration project for China-Uzbekistan building materials trade cooperation, facilitating the regular entry of high-quality Uzbek products into Xinjiang and their distribution across China.

Ding Guochong, chairman of Xinjiang Zhongzhi Digital Technology Co., Ltd., said the event not only showcased Uzbek specialty products but also helped Chinese enterprises and local Xinjiang products reach markets in Central Asia. The Urumqi Bonded Exhibition and Trading Center currently houses products with over 17,000 items from nearly 80 countries, and introduces new products at a rate of nearly 15% each month. In the first half of this year, sales exceeded 13 million yuan (about $1.81 million), with cumulative foot traffic surpassing 120,000. The event was hosted by the Ministry of Investment, Industry and Trade of the Republic of Uzbekistan and organized by the Urumqi Bonded Exhibition and Trading Center and Xinjiang Zhongzhi Digital Technology Co., Ltd.
