China's largest ever high-tech trade fair concluded on Sunday, showcasing China's strength in technological innovation with global companies expressing their desire to actively engage in cooperation with Chinese enterprises and confidence in the Chinese market.

As the latest aspect of China's opening-up, the event has played an active role in facilitating exchanges and cooperation in technology between China and countries worldwide, driving global technological advances and innovative development, experts said.

The 25th China Hi-Tech Fair 2023, the largest ever in terms of global participants in its history, came to a close on Sunday, with more than 680 new products unveiled and a cumulative negotiated transaction amount surpassing 37 billion yuan ($5.13 billion) as of press time. 

With a record exhibition area of 500,000 square meters, a total of 4,925 companies signed up for the event, capturing opportunities to showcase their technological capabilities and foster collaboration, achieving an all-time high.

A number of China's technological breakthroughs were showcased at the fair.

The Chinese Academy of Sciences showcased a domestically developed computer numerical control system, which is widely known as an industrial mother machine. The system, with its fast response speed and high precision, will provide reliable technical support for strategic emerging industries such as aerospace and new-energy vehicle manufacturing, breaking the long-standing technological monopoly of foreign countries, China Media Group reported.

Xpeng Aeroht, the largest flying carmaker in Asia and affiliate of XPeng Inc, premiered a futuristic "flying car" at the event. The car can switch between driving and flying modes. While remaining in compliance with regulations and environmental conditions, it can vertically take off and land, enabling it to fly over congested areas, obstacles and rivers, meeting the demand for short-distance low-altitude travel. 

The product will also be shown in the Consumer Electronics Show in North America in January next year, showcasing the charm of Chinese technology to the world, the Global Times learned from Xpeng Aeroht.

The annual event, inaugurated in 1999, is the largest and the most influential science and technology fair in China. After 25 years of development, the fair has become an important platform for companies from around the world to share opportunities in China.

Siemens Energy showcased its hydrogen solution - Silyzer 300 - at the event. The Silyzer 300 is a modular hydrogen electrolysis system that goes up to the three-digit megawatt range and is the latest and most powerful proton exchange membrane electrolysis portfolio available now from Siemens Energy.

"China is undergoing one of the largest energy transitions in human history. This is not just about a shift of the energy mix in its traditional sense, but also involves local cooperation and scientific innovation at a higher level and with a faster speed. This presents a broader scope of cooperation for leading global energy technologies companies like Siemens Energy," Anne-Laure Parrical de Chammard, a board member of Siemens Energy AG, said in a statement sent to the Global Times on Sunday.

US carmaker Tesla unveiled the refreshed Model 3 and the upgraded Model Y at event with improved design, cabin and performance, demonstrating China's manufacturing prowess and cutting-edge technology.

As a testament to the success of its "Made in China" vehicles, Tesla's Shanghai Gigafactory, the carmaker's major export hub, delivered 771,000 vehicles from January to October this year, surpassing the projected annual delivery figure for 2022, Tesla told the Global Times in a statement on Sunday.

The China Hi-Tech Fair had attracted companies from 105 countries and regions and 248,000 visits as of Sunday at noon, both record highs, the China Media Group reported.

The eagerness shown by global participants and all-time highs in their scale and participation demonstrated China's growing strength and attractiveness in the field of technology, Wang Peng, an associate researcher at the Beijing Academy of Social Sciences, told the Global Times on Sunday.

The fair plays a positive role in promoting industry chain and technological cooperation, where companies and institutions from different countries can showcase their latest technologies and products, seek partners and facilitate exchanges and collaboration, Wang noted.

In a video speech at the fair's opening ceremony, Guo Tingting, a vice minister of the Ministry of Commerce, expressed China's commitment to strengthening its high-standard opening-up and fostering a more dynamic and inclusive innovation ecosystem. 

China will make proactive efforts to integrate into the global innovation system, deepen trade and investment cooperation, and share the benefits of opening-up and innovation with all nations, Guo said.
