����Practice has proven that as a complex systemic project�� the BRI can not only offer concrete services in infrastructure facilities�� financial integration and unimpeded trade�� but also contribute to intangible areas such as concept and system. The BRI has turned from a vision into reality�� from Eastern wisdom to a public product for the world.����Fruitful Results����Four years since its proposal�� the BRI has achieved far more than expected. Practice has proven that the BRI is able to provide the world with material and conceptual public products that promote connectivity�� common development and global governance.����1. Effective connectivity. Generally connectivity is mainly about infrastructure�� personnel and systems and regulations�� providing guidance over integration at deeper levels in BRI countries and regions. Infrastructure connectivity is an important component of the BRI�� and after four years' time significant progress has been made in this regard�� with a pan-Asian railway network taking shape�� transnational railways running from Asia to Europe�� and sea ports under construction. People-to-people ties are the social foundation of the BRI. To enhance such ties relevant policies have been introduced to make visa application easier between BRI countries. Connectivity in systems and regulations ensures the BRI proceeds smoothly. By connecting strategically and opening free trade zones�� BRI countries should follow the principles of openness�� inclusiveness�� sharing of benefit�� and balanced growth to build bilateral�� multilateral�� regional�� and global free trade zones at different levels and in different types.����2. Innovation in new-type international financial institutions. The Silk Road Fund and the AIIB are both public financial products China provides to the international society�� both concrete steps it takes for the BRI. Compared with other financial institutions�� the AIIB and the Silk Road Fund are pragmatic with new governance rules and standards�� diverting more attention to developing countries and their need for financing. It is through these two organizations that China takes part in global financial governance with action�� reforming the international monetary system�� and increasing public goods supply in the financial sector. These two institutions are also conducive to reforming and recreating trade and investment rules�� improving financial and monetary mechanisms�� and building a fairer and more rational framework of a new economic order.��������
