Opening up is a distinctive symbol of Chinese path to modernization. To build a new system of higher-level open economy, it is necessary to continuously combine the new situation and tasks of open development, and provide new policies and measures. In July of this year, the Ministry of Commerce, the People's Bank of China, and other four departments jointly issued the "Opinions on Strengthening the Coordination of Commerce and Finance and Supporting the High quality Development of Cross border Trade and Investment with Greater Efforts" (referred to as the "Opinions"), which put forward 11 policy measures. This not only demonstrates China's firm determination to promote high-level opening up to the outside world, but also meets the practical needs of expanding cross-border trade and investment, playing a "chain trick" and "combination punch" of policies, which is very worthy of attention. This new initiative to expand openness is highly targeted in the current global economic situation. From an external perspective, the International Monetary Fund (IMF) expects global economic growth to remain unchanged at 3.2% in 2024, while global trade volume is expected to increase by 3.1% and 3.4% in 2024 and 2025, respectively. IMF Chief Economist Pierre Olivier Gulancha warns that if developed economies struggle to curb inflation, central banks, including the Federal Reserve, may need to maintain borrowing costs at higher levels for a longer period of time, which could have negative spillover effects on emerging and developing economies. From an internal perspective, the continuous deepening of China's own economic structural adjustment since the beginning of this year has also brought some new challenges. However, factors such as the sustained release of macroeconomic policy effects, the recovery of external demand, and the accelerated development of new quality productivity have also formed new support. China remains an important engine and stabilizing force for world economic growth. At the same time, the development of new industries, new formats, and new business models has brought new vitality to cross-border trade and investment, and put forward new requirements for open policies. In practice, foreign trade enterprises face issues such as exchange rate risks, financing difficulties, and cumbersome settlements. "Going global" enterprises face challenges such as compliance requirements and cross-border payments, and foreign-funded enterprises also look forward to further optimizing their business environment. To solve these problems, there is an urgent need for stronger policy collaboration. At this point, the Opinion has made targeted and specific arrangements. For example, in terms of financing, banks and insurance institutions are encouraged to provide high-quality financial services for cross-border e-commerce and overseas warehouse enterprises based on real and reliable data elements such as order flow, logistics, and fund flow; In terms of optimizing the business environment, we will focus on building the "Invest in China" brand and increase efforts to attract "specialized, refined, unique, and new", "hidden champions", and key supply chain enterprises; In terms of building an open platform, high-quality hosting of major exhibitions such as the China International Import Expo, Canton Fair, China International Fair for Trade in Services, China International Fair for Trade in Investment and Development, and China International Fair for Trade in Services... High level openness and high-quality development complement and promote each other. High level opening up promotes the flow and integration of domestic and foreign factor resources, which is an inherent requirement and important means to achieve high-quality development. High quality development provides a solid foundation and conditions for promoting high-level opening up through continuous optimization of industrial structure and improvement of market system. At present, China's opening up to the outside world has reached a new historical starting point, requiring the implementation of a larger scale, wider scope, and deeper level of opening up to the outside world. It is necessary to build a new system of higher-level open economy to provide strong institutional and mechanism guarantees for high-quality economic development. Objectively speaking, high-level opening up to the outside world is a systematic project that involves a wide range of aspects. It requires strengthening the coordination and cooperation between trade policies and financial, investment, fiscal, regional and other policies, focusing on deepening institutional and mechanism reforms in key areas, and taking into account the practical needs of enterprise development. This requires us to mobilize various forces and resources to promote the formation of a policy synergy of high-level openness and high-quality development. For enterprises, policy synergy can provide a stable, efficient, and predictable policy environment, which helps them better achieve long-term strategic planning, enhance their innovation capabilities and international competitiveness, better and faster integrate into the world economy, and share the dividends brought by economic globalization. Overall, the effectiveness of the Opinion is worth looking forward to.
