The universality and importance of poverty issues on a global scale were discussed, emphasizing China's tremendous achievements in poverty reduction and its reference significance for other developing countries. The article points out that China's global development initiative aims to strengthen the exchange of development experience and capacity building cooperation with other countries by building a global development knowledge sharing network. Development knowledge, like capital, is an important development resource. China's development experience not only helps promote Chinese path to modernization, but also provides reference for other developing countries. The article also mentions that knowledge sharing is an important part of global poverty governance, playing a crucial role in improving the efficiency of resource utilization and enhancing poverty governance capabilities in recipient countries. Compared to the foreign aid of developed Western countries, parallel sharing of development experience among developing countries is conducive to building a new type of aid relationship. The article takes China's assistance to poverty reduction cooperation in Cambodia as an example to analyze how China combines its development experience with the needs of recipient countries and jointly promotes the practice of international poverty reduction goals. China's aid and development cooperation to Cambodia has lasted for more than 60 years, covering the entire process of Cambodia from striving for national independence to national political and economic revitalization and development. Cambodia has achieved remarkable results in poverty reduction, and China's assistance to Cambodia in poverty reduction cooperation has achieved positive results. It has helped Cambodian policy makers at all levels understand the formulation and implementation of China's poverty reduction policies, and has influenced the formulation and implementation of poverty reduction policies in Cambodia through various channels such as experience sharing in governance, youth cadre training courses, and skills training courses. China's assistance to Cambodia for poverty reduction cooperation is based on the actual development of developing countries, and has established a three-tier knowledge sharing body of "central government local government business community grassroots practitioners". Through the sharing carriers of macro, meso, and micro levels, development experience sharing has been carried out, and it has successfully influenced the formulation of poverty reduction policies in recipient countries.

1、 Knowledge sharing and capacity building for recipient country development

The importance of knowledge sharing in international cooperation, particularly in addressing poverty issues in recipient countries, was discussed. As a pioneer in knowledge sharing, the World Bank promotes education aid development through a dual tool of finance and knowledge. The article takes the trilateral cooperation between the World Bank and China in Vietnam as an example to demonstrate the effectiveness of knowledge sharing in healthcare system reform. This article focuses on the coordination of diverse subjects in knowledge sharing, the institutional design of knowledge development in China, and how to apply it locally based on the actual situation in Cambodia. Knowledge sharing includes three processes: knowledge acquisition, dissemination, and application, aimed at promoting sustainable economic and social development in recipient countries. Developing countries need to accumulate intellectual capital, social capital, and political capital to solve poverty problems, and knowledge sharing is an important way to build capacity. Material assistance and knowledge sharing are indispensable means to enhance the development capacity of developing countries, and technical assistance under the framework of South South cooperation is also part of the accumulation of intellectual capital.

2、 The History of China's Aid to Cambodia

A detailed review of China's aid history to Cambodia shows that since the 1950s, China's economic and technological assistance to Cambodia has continued to increase, especially after 2009, with an annual aid amount exceeding 100 million US dollars. The content and methods of assistance are diversified, with a focus on infrastructure construction and production-oriented projects such as bridges, roads, and water conservancy projects. The education sector has also received assistance from China, such as the Kratie Agricultural Technology School and the Kratie University project. The Chinese social strata actively participate in grassroots livelihood project assistance, such as the construction of hospitals, schools, and agricultural irrigation and drainage pump stations. Sihanoukville Port Special Economic Zone is a landmark project for China and Cambodia to jointly build the "the Belt and Road". The bilateral free trade agreement between China and Cambodia has come into effect, further promoting economic and trade cooperation between the two countries. During the third "the Belt and Road" International Cooperation Summit Forum, China and Cambodia signed a number of cooperation documents covering many fields. China has become Cambodia's largest trading partner, investor, source of tourists, and development aid partner. Cambodia attaches great importance to the export of agricultural products, and China is its largest export market. Cambodia's GDP will grow by 5.4% in 2022, with growth in industry, services, and agriculture. The role of China's poverty reduction cooperation mechanism and knowledge sharing in aid to Cambodia deserves further exploration.

3、 Knowledge sharing and China's assistance to Cambodia's poverty reduction cooperation path

This chapter explores the knowledge sharing path of China's cooperation in poverty reduction in Cambodia, mainly implemented through three processes: developing knowledge supply, disseminating and localizing knowledge. The experience of poverty reduction in China is the main source of knowledge for assisting Cambodia in poverty reduction cooperation, thanks to strong organizational guarantees and solving poverty problems in the process of economic development. China focuses on vulnerable groups through the strategy of "targeted poverty alleviation" and special assistance policies, promoting economic growth to drive capital accumulation and employment to ensure people's livelihoods. China's experience in poverty reduction and development is shared with the world through bilateral and multilateral development assistance platforms.

4、 Challenges and Countermeasures in Knowledge Sharing of China's Poverty Reduction Experience

China's poverty reduction cooperation with Cambodia has achieved significant results through the comprehensive use of basic, industrial, and ecological poverty reduction models, as well as direct investment, bilateral trade, and humanitarian aid, effectively reducing poverty in Cambodia. However, cooperation faces challenges such as insufficient coordination among knowledge sharing entities, low content matching, and the need to improve coordination among aid providers. To overcome these obstacles, it is necessary to strengthen top-level design and planning, improve the matching of knowledge with actual situations, mobilize private forces, use multi-channel communication and exchange platforms, share and disseminate poverty reduction assistance knowledge, and improve the efficiency of cooperative poverty reduction.

5、 Conclusion

The importance of knowledge sharing in international development cooperation was emphasized, and it was pointed out that there is insufficient attention to knowledge sharing in current international aid. The article analyzes China's poverty reduction assistance to Cambodia and explores the obstacles and coping strategies of knowledge sharing in poverty reduction cooperation. The paper proposes that knowledge sharing, as a new form of assistance, has important reference value for the construction of the "the Belt and Road" and South South cooperation, and is conducive to building a global development community.
