Currently, the world's century long changes are accelerating, and the world economy is facing multiple risks and challenges. The recovery is weak, and unstable, uncertain, and unpredictable factors are increasing. At this time, how to promote sustainable development of the world economy? At the sub forum with the theme of "Promoting Economic Recovery and Global Cooperation", the attending guests expressed their own opinions and jointly discussed solutions. In the view of former Nigerian President Olusegun Obasanjo, many countries around the world are currently facing economic downturn pressure and should work together to expand the economic "cake" and benefit global development. He mentioned that by 2050, the population of Africa is expected to exceed 2.5 billion, which is a market full of development opportunities and an indispensable part of the global cooperation puzzle. Regarding this, Zou Chiyong, the representative and executive director of the United Nations Industrial Development Organization, is deeply convinced. He stated that financial cooperation is an important part of global cooperation, and helping countries with higher levels of development to obtain low interest loans can accelerate the latter's pace of enhancing development capabilities, which is more conducive to promoting global economic recovery. Ismail Salagordin, former Vice President of the World Bank and Co Chairman of the Nizami Gandavi International Center, has long been concerned about global poverty reduction. He is deeply impressed by China's achievements in eliminating absolute poverty, stating that "poverty reduction is an important aspect of the United Nations Millennium Development Goals and the 2030 Agenda for Sustainable Development, and China has done very well in this regard."? Saragordin observed that the global economy is currently undergoing transformation, and it is even more necessary for the world to work together, innovate the use of multiple funds, promote active assistance between countries, and encourage private investors to participate in low-carbon and energy-saving green projects, in order to promote the transformation process of the global economy. In the forum speech, multiple attending guests emphasized the importance of the private economy. Xiang Songzuo, former Chief Economist of Agricultural Bank of China and President of Shenzhen Dawan District Financial Research Institute, believes that the private economy has great development potential. Countries should continue to create a more open and transparent business environment, introduce more incentive policies for the development of the private economy, enhance its vitality and confidence, and then drive global economic growth.
