According to the First Financial Report, at the recent annual meeting of the China International Finance Society in Beijing, Jeffrey Sachs, a professor of economics at Columbia University in the United States, pointed out that world politics has now changed from a US-led to a multi-polar, multi-currency pattern that is very different from it. Only a more active global cooperation can smoothly survive today's fragile and unstable period. Sachs believes that East Asia has become the most innovative region in the world. China, Japan and South Korea play a driving role in the development of the digital economy, and China's patent applications are already far ahead in the world. He believes that these huge economic turning points are the embodiment of the world's transition from unipolar leadership to multipolarity in the United States. In the digital revolution, the world should not be divided by technology, but should try to make science and technology promote the unity of the world. For any dangerous behavior, countries should use a high level of mutual trust and understanding to resolve it. He pointed out that it is intolerable and unwise to use a currency as a political tool against other countries, and the internationalization of the renminbi can provide more means of payment for the international community.
