The four-day expo, which runs from Thursday to Sunday, features more than 200 local and international exhibitors.
A significant portion of these participants comprises Chinese companies across four core sectors: machinery and automation, textiles and garments, plastics and rubber, and printing and packaging.
Organized by Yorkers Trade & Marketing Service Co., Ltd. in collaboration with the Ministry of Industry, Science, Technology & Innovation, the expo provided a platform to showcase emerging industrial technologies, foster business connections and support the modernization of Cambodia's manufacturing sector.
According to official ministry data, Cambodia had 3,357 operational factories as of July 2026. These facilities employ over 1.35 million workers, more than 70 percent of whom are women.
Total factory investment in the kingdom reached approximately 28 billion U.S. dollars, a 29 percent increase compared to the same period in 2025. Additionally, industrial production during the first half of 2026 was valued at over 9.8 billion dollars, including roughly 7.3 billion dollars in goods manufactured for export.
Cambodian Minister of Industry, Science, Technology and Innovation Hem Vanndy urged Cambodian enterprises to embrace advanced technologies to boost productivity, improve quality, and sharpen their competitive edge.
"Artificial intelligence, production-line automation, robotics, digital technologies and smart manufacturing are increasingly determining the competitiveness of nations," he said during the expo's opening ceremony on Thursday.
"Cambodia cannot remain outside this transformation," Vanndy said. "We must embrace new technologies to increase productivity, reduce costs, improve product quality and strengthen the competitiveness of our enterprises."
Chim Vinly, the expo's organizing staff member, said the exhibition plays a vital role in introducing innovative manufacturing technologies to Cambodia's garment sector, as attendees can explore a diverse range of advanced machinery designed to elevate production standards.
"Most exhibitors represent the textile and garment industries, with the majority being local and Chinese companies," he told Xinhua on Saturday.
"These advanced manufacturing tools have boosted productivity and modernized local production chains. In particular, they make work faster and more efficient," he added.
Vinly said the annual event plays a vital role in further expanding bilateral trade between China and Cambodia.
"Chinese investment is crucial to boosting Cambodia's economic growth and generating job opportunities for the local workforce," he said.
Bo Seyma, a mechanic at Kosin Sewing Machine Co., Ltd., which supplies Cambodian factories with equipment from the Shanghai-based Shang Gong Group, said the expo is vital for showcasing cutting-edge machinery to the local garment industry.
He said the Kosin company is promoting sewing, embroidery, button, and backstitching machines, along with other equipment, to factories in Cambodia.
"These industrial machines are in high demand, with numerous factories placing purchase orders with our company," he told Xinhua on Saturday.
Seyma said these advanced machines are high-quality and built to last.
"These machines accelerate production efficiency while effortlessly meeting customer demands," he said.
Thong Mengdavid, deputy director at the China-ASEAN Studies Center of the Cambodia University of Technology and Science, said that Cambodia, a country heavily dependent on textiles and garments, has seen its cooperation with China evolve from providing raw materials like fabrics and finished consumer goods toward technological cross-pollination.
This allows local Cambodian plant managers and entrepreneurs to evaluate high-grade machinery directly, he added.
"Integrating China's technology, machinery, and tools into Cambodian factories will address several challenges in the local economy, such as enhancing output per hour, reducing material waste caused by human error, and fostering skill development among the workforce," Mengdavid said.

。    跟启发它的螃蟹一样，该机器人利用其各向异性的腿垂直挖掘颗粒状介质--各向异性允许材料在不同方向移动时表现出不同的特性。螃蟹有10条腿，而EMBUR只有4条。跟螃蟹的情况一样，机器人通过交替使用身体一侧的所有腿进行挖掘，然后再使用另一侧的所有腿进行扫荡。

二 | 在EMBUR上，每条腿都采取了可延伸金属轴的形式，并有一条沿其纵向延伸的织物。当腿在“动力冲程”中离开机器人的身体时，它就会拉长并将织物拉紧--这使得织物的作用有点像一个篮子，能收集和置换颗粒状介质。当腿被拉回身体时它就会缩短，并导致织物下垂和穿过颗粒物，而不是收集它们。

三 | 通过快速重复这些动作，EMBUR可以相对快速地埋葬自己。并且，机器人关节上的所有开口都覆有一层橡胶膜，这使得它们能自由移动，与此同时还能防止颗粒物进入并堵塞一切。

四 | 在Hannah Stuart助理教授的领导下，科学家们现在正在努力使该机器人能在实际的沙子和泥土中挖掘。希望它的后代有一天能被用于评估农业和建筑工地的土壤并从洋底收集科学数据，甚至还可以作为海洋车辆或航天器的锚。
