Regionalism emerged globally after World War II, and the development of regionalism around China was limited, requiring theoretical innovation. Since the 1990s, the academic community has conducted comprehensive research on the development of China's peripheral integration after the Cold War, but there is a lack of evidence on the direction for improvement. In 2013, China proposed the concept of a community with a shared future for its neighboring countries, breaking through traditional international relations concepts and aiming to promote cooperation and development with neighboring countries, as well as improve and upgrade regionalism.

1、 The Development and Characteristics of Regionalism around China Since the End of the Cold War

Regionalism, as an emerging global development model after World War II, promotes cooperation among countries in the region in areas such as economy and security through the formation of regional organizations, forming mutually beneficial and interdependent relationships between countries. Regionalism around China originated in the 1960s and has gone through four stages of development: germination, expansion, rapid development, and relative stagnation. The embryonic period (early 1960s to late 1980s) was marked by the establishment of the Association of Southeast Asian Nations and Japan's promotion of regional cooperation ideas. The expansion period (1990-1997) was characterized by the expansion of ASEAN and a renewed attempt at East Asian regionalism. The rapid development period (from the outbreak of the Asian financial crisis in 1997 to 2012) was characterized by the "10+X" cooperation framework and the construction of regional communities. The period of relative stagnation (2013-2019) progressed slowly due to US intervention and regional order competition, but the signing of the Regional Comprehensive Economic Partnership (RCEP) in 2020 marked the recovery of the East Asian integration process.

2、 The Ideal State of Regionalism Development and the Limitations of Regionalism in China's Surrounding Regions

Regionalism, as a new model for the development of international relations after World War II, has strengthened cooperation among countries in the region and promoted overall prosperity and stability. Ideally, regionalism requires the construction of a unified regional identity, transcending national centrism, strengthening the overall interests of the region, and the achievement of regional cooperation that transcends barriers of national scale and development level, benefiting all countries together. However, disputes over interests in reality often lead to the actual development of regionalism deviating from the ideal state and facing limitations in reality.

3、 The concept of a community with a shared future in the surrounding areas: a new theoretical paradigm for the development of regionalism

Since the 21st century, the world has faced challenges such as great power competition, geopolitical frictions, weak economic growth, and frequent hot issues. China proposed the concept of a "community with a shared future for mankind" in 2012 and further proposed the concept of a community with a shared future for its neighbors in 2013, aiming to create a peaceful and stable Asian environment. The concept of a community with a shared future in the surrounding areas has broken through the limitations of traditional Chinese regionalism and provided a new theoretical paradigm for the development of regionalism. Its theoretical connotation emphasizes overall interests, equality between countries, and the pursuit of universal values, which contrasts with the power centered structural system of the international community and the cooperative relationship between countries with self-interest as the core. This concept has three significant characteristics: emphasizing the whole rather than the individual, highlighting equality rather than strength, and seeking universality rather than universality. Practicing the concept of a community with a shared future in the surrounding areas will help deepen the friendly relations between China and neighboring countries, open up new opportunities for cooperation, and provide important theoretical solutions for addressing the development of regionalism in China's surrounding areas. The concept of a community with a shared future in the surrounding areas has guiding significance for promoting the development of regionalism in China's surrounding areas, including promoting the construction of regional identity, emphasizing interdependence rather than conflict and competition, sharing development results to achieve win-win outcomes, emphasizing openness and inclusiveness in implementing global initiatives, and so on. This concept breaks through the narrow view of interests and is more in line with the needs of the times, providing guidance for solving the problems and future development of regionalism in China's surrounding areas.

4、 The concept of a community with a shared future in the surrounding areas: a new path of action to address the limitations of current development

Explored the innovation and application of the concept of a community with a shared future in both theory and practice. The concept shows its unique advantages through material cooperation mechanisms such as the "the Belt and Road" initiative and the construction of the Asian Investment Bank, as well as the construction of multilateral mechanisms at the security level, such as the cooperation framework between China and ASEAN. China promotes the "the Belt and Road" initiative and the Asian Investment Bank, strengthens cooperation with neighboring countries, forms a strategic alignment, connectivity and production capacity cooperation layout, and promotes connectivity and economic and trade industry development with Southeast Asian countries. The Asian Investment Fund provides financial support for the "the Belt and Road Initiative" and promotes infrastructure construction in developing countries. In terms of security, China suppresses hegemonic behavior through multilateral security mechanisms, promotes regional peace and stability, supports the central position of ASEAN, and promotes the Asian approach to resolving differences. The concept of a community with a shared future in the surrounding areas solves problems in regionalism through cooperation initiatives and mechanisms, provides open, inclusive, mutually beneficial international public goods and cooperation platforms for China's neighboring regions, highlights multilateralism, adheres to development priority, and is committed to mutually beneficial cooperation, becoming the latest action guide for promoting the development and upgrading of regionalism.

conclusion

Since the 1960s, regionalism around China has gone through four stages of development, forming a cooperative pattern characterized by openness, inclusiveness, and weak mechanisms. However, current regionalism has problems such as incomplete development and lack of motivation, which fall short of ideal characteristics. The concept of a community with a shared future for mankind and its derivative concept of a community with a shared future for neighboring countries provide a new solution for the breakthrough and development of regionalism in China's neighboring regions. This concept helps to build regional consensus, goes beyond national centrism, emphasizes the sharing of development outcomes, and conforms to the ideal characteristics of regionalism. At the same time, the concept of a neighborhood community with a shared future has established a material and security guarantee mechanism, promoted regional development and concept dissemination through cooperation initiatives such as the "the Belt and Road", and embodied the characteristics of open and inclusive regionalism. The concept of a community with a shared future for mankind has broken through existing international relations theories, providing theoretical and practical guidance for the upgrading of regionalism in China's surrounding areas, and is expected to achieve a true upgrade of regionalism.
