Attendees of a Silicon Valley conference from China and the US said they're optimistic about the long-term prospects for growth.

Chinese entrepreneurs and their US counterparts are getting together in Silicon Valley through a variety of events that included more than 2,000 attendees from both sides. Some of the participants found new partners as they aim to apply new technologies in businesses.

XIONG WEI, VICE DIRECTOR FOSHAN NANHAI GUANGDONG TECHNOLOGY UNIVERSITY CNC EQUIPMENT COOPERATIVE INNOVATION INSTITUTE "I came here with several agreements. Technological cooperation is on the rise both in China and overseas. Foshan has strong demand in smart manufacturing and Silicon Valley has the talent and technologies we need."

This gathering of Chinese and US entrepreneurs isn't the first of its kind in Silicon Valley. That's because the two countries play leading roles in innovation. The US audit and consultancy firm Deloitte says in a new report that China and the US are host to 80 percent of the world's unicorns firms. The business sentiment between the two countries in the tech investment has continued despite ongoing trade frictions.

ZHAO ZHENGE, GENERAL REPRESENTATIVE CHINA COUNCIL FOR THE PROMOTION OF INTERNATIONAL TRADE "The past two sessions and President Xi's remarks at the Boao Forum all sent out a message that China will take more measures to open up its market and more sectors. That includes bio-pharmacy and electric cars. This is good news for the US business world. They are closely following our opening-up and hope to grab more shares in a growing market."

Some US attendees believe a trade war is not a remedy to fix any imbalances. They worry that the downside of China-US relations might affect the already internationalized local economy.

Meanwhile, most attendees are optimistic and hope the page on trade friction can be turned as soon as possible.
