URUMQI, Sept. 5 (Xinhua) -- The first China-Eurasia Expo that concluded Monday in Urumqi, capital of northwest China's Xinjiang Uygur Autonomous Region, has clinched trade and technical cooperation contracts worth about 130 billion U.S. dollars, expo organizer said.

Among all contracts, 5.5 billion dollars are clinched between Chinese and foreign companies, while 124 billion dollars are among Chinese companies, the organizer said.

About 50,000 officials and business people from China and about 30 countries, regions and international organizations attended the trade fair, which also attracted an audience of more than 300,000 people.

The event was upgraded from the 19-year-old China Urumqi Foreign Economic Relations and Trade Fair, a regional trade fair, last year.

The fair covered an area of nearly 80,000 square meters for its more than 4,000 exhibition booths, according to the organizer.
