A three-day business and investment summit between China and ASEAN countries is scheduled to open Sept 12 in South China's Guangxi Zhuang autonomous region, the regional government said Monday.

The 14th China-ASEAN Business and Investment Summit, to be held in the regional capital of Nanning, will focus on building the 21st Century Maritime Silk Road and promoting regional economic integration via tourism.

Government officials, industry representatives and business leaders will participate in various events regarding cross-border e-commerce, business and legal cooperation, investment conferences and Belt and Road construction.

As of July, the China-ASEAN cross-border e-commerce platform had closed 824,000 deals involving 909 types of goods. Indonesia, Vietnam and Malaysia ranked the top three in terms of trade volume.

A roundtable will also be held between state leaders of Brunei and CEOs of Chinese companies during the summit.

The summit was first held in 2004.
