BEIJING - Business leaders of G20 members will focus on promoting robust, sustainable and balanced growth of the global economy during the September summit, an official said Thursday.

The Business 20 (B20) summit will gather nearly 1,000 business leaders in east China's Hangzhou city on Sept 3 and 4, said Yin Zonghua, vice chairman of the B20 2016 Host Committee and vice president of the China Council for the Promotion of International Trade.

The summit will have six issues on its agenda: financing growth, trade and investment, infrastructure, small- and medium-sized enterprise (SME) development, employment and anti-corruption, Yin told a press conference.

The business leaders have formed a draft report on policy advice for G20 leaders including topics such as green financing, a global e-trade platform, international investment and business transparency, he said.

The report will be submitted to the G20 summit, which will be held in Hangzhou on Sept 4 and 5 under the theme "towards an innovative, invigorated, interconnected and inclusive world economy."

B20 attendees produce policy recommendations for the annual meeting of the G20 leaders. It brings together G20 business leaders to reflect upon the role of the private sector as the main driver of economic growth.
