LANZHOU - The 31st China Lanzhou Investment and Trade Fair opened on Sunday in Lanzhou, the capital of Northwest China's Gansu province, attracting over 2,000 domestic and international enterprises.

This year's fair features Indonesia as its guest country of honor. Participation has surpassed previous fairs, with representatives of over 20 nations, including Germany, Spain, Russia, Malaysia and Iran, attending alongside representatives of 18 Chinese municipalities, provinces and autonomous regions, as well as the Hong Kong Special Administrative Region.
