On June 28, 2021, General Secretary of the Communist Party of China (CPC) Xi Jinping sent a congratulatory letter to President of the Cambodian People's Party (CPP) Samdech Techo Hun Sen on the 70th anniversary of the CPP's founding.

Xi Jinping said in the congratulatory letter that on the occasion of the 70th anniversary of the CPP's founding, I would like to extend warm congratulations to President Hun Sen, the CPP and the Cambodian people on behalf of the CPC and the Chinese people, as well as in my own name.

Xi Jinping pointed out that for a long time, the CPP has been uniting and leading the Cambodian people in advancing the cause of national construction and development, making positive contributions to regional stability and prosperity. China, as always, will support Cambodia in pursuing a development path that suits its national conditions. I believe that under the right leadership of President Hun Sen, the CPP will continue to make new and greater contributions to the prosperity of Cambodia and the happiness of the Cambodian people, as well as to regional peace and development.

Xi Jinping stressed that China and Cambodia are staunch friends and a community with a shared future. Bilateral relations have been enjoying high-level development. Since the outbreak of the COVID-19 pandemic, the two sides have pulled together and helped each other, vividly illustrating the unbreakable and everlasting friendship between China and Cambodia with concrete actions. The CPC attaches great importance to the friendly cooperation with the CPP. I am willing to work with President Hun Sen to strengthen the political guidance for the relations between the two countries and between the two parties, deepen exchanges and cooperation between the two parties and in other fields, and promote the building of the China-Cambodia community with a shared future, so as to bring benefits to both countries and the two peoples.
