# China: Cambodia’s Longstanding Ally - Link: https://www.thailand-business-news.com/asean/cambodia/46723-china-charms-cambodia - Published: 2025-03-06T14:00:44+07:00 - Author: Changyong Rhee Cambodia’s enduring alignment with China was prominently showcased in 2012 when, as ASEAN Chair, it declined to address territorial disputes in the South China Sea. This widely discussed episode highlighted the deep and strategic ties between the two nations. Cambodia’s alignment with China comes as no surprise, given the clear advantages of being one of China’s most favored partners. The nation benefits significantly from Chinese investments as well as economic and military aid, both monetary and material, often provided with “no strings attached.” ADVERTISEMENT China has emerged as Cambodia’s largest trading partner and investor, playing a pivotal role in its economic development. By 2021, China invested $2.32 billion, a 67% increase year-on-year, and had provided approximately $4.2 billion in official development assistance by 2017, including grants and soft loans. * China appears to be Cambodia’s enduring and influential ally, often referred to as a “long-time friend” due to their historical and ongoing ties. * Research suggests their relationship is rooted in centuries of cultural and commercial exchanges, with modern economic and political cooperation strengthening this bond. * The evidence leans toward China being Cambodia’s largest trading partner and investor, with recent projects like the Funan Techo Canal highlighting their partnership. ## Historical Context China and Cambodia have shared cultural and commercial ties since at least the Tang Dynasty, with early trade relationships shaping their historical friendship. In modern times, China supported Cambodia during conflicts like the Cambodian-Vietnamese War, further solidifying their alliance. ## Current Relationship Today, China is Cambodia’s largest investor and trading partner, providing significant aid and backing major infrastructure projects. Recent high-level meetings, such as the April 2024 visit by Chinese Foreign Minister Wang Yi, underscore their “iron- clad” friendship and comprehensive strategic partnership. Unexpected Detail While China dominates, Cambodia also maintains historical ties with Russia, another“ old friend,” though Russia’s current influence is less prominent compared to China’s extensive economic engagement. --- Survey Note: Detailed Analysis of China-Cambodia Relations China’s relationship with Cambodia, often described as that of a “big old friend,” is a multifaceted alliance rooted in centuries of history and reinforced by contemporary economic and political cooperation. This note explores the historical context, current dynamics, and recent developments, providing a comprehensive overview for readers interested in international relations. Historical Foundations The ties between China and Cambodia date back to at least the Tang Dynasty, with the first recorded contacts occurring during this period. Historical accounts, such as those from the Yuan Dynasty, highlight a strong trading relationship, with a Chola-Song-Khmer trade axis dominating eastern trade in the 11th and 12th centuries( [Cambodia–China relations – Wikipedia](https://en.wikipedia.org/wiki/Cambodia%E2%80%93China_relations)). The Chinese community in Cambodia, constituting 3-5% of the population (approximately 950,000 people), has been a prominent business community, despite facing discrimination during the Khmer Rouge era and Vietnamese occupation. This historical presence underscores a deep cultural exchange, with early diplomatic ties established as early as 1421 AD during the Ming Dynasty. In the mid-20th century, China’s support for the Khmer Rouge during the Cambodian Civil War and against Vietnamese forces in 1978 further shaped their relationship. This support included military and political backing, with China waging a brief border war against Vietnam in 1979 to pressure it to withdraw from Cambodia ([Cambodia–China relations – Wikipedia](https://en.wikipedia.org/wiki/Cambodia%E2%80%93China_relations)). The Paris Peace Conference on Cambodia (1989-1991) marked a turning point, resolving tensions and paving the way for closer ties since 1997, particularly with Prime Minister Hun Sen’s regime. Current Economic and Political Dynamics In the present day, China has emerged as Cambodia’s largest trading partner and investor, playing a pivotal role in its economic development. By 2021, China invested $2.32 billion, a 67% increase year-on-year, and had provided approximately $4.2 billion in official development assistance by 2017, including grants and soft loans( [Cambodia-China friendship unbreakable – NDRC](https://en.ndrc.gov.cn/news/mediarusources/202211/t20221107_1340948.html)). This investment has financed critical infrastructure, such as over 2,000 km of roads, seven large bridges, and a new container terminal at Phnom Penh Autonomous Port, largely through the Belt and Road Initiative (BRI) launched in 2013 ([Cambodia-China Relations in the New Decade – Konrad-Adenauer-Stiftung](https://www.kas.de/en/web/kambodscha/single-title/-/content/cambodia-china-relations-in-the-new-decade-2)). Politically, the relationship is characterized by a “comprehensive strategic partnership” upgraded in 2010, with frequent high-level engagements. In April 2019, both nations signed the “Action Plan 2019-2023 on Building China-Cambodia Community of Shared Future,” committing to 31 measures across politics, security, economics, people- to-people relations, and multilateral cooperation ([Cambodia-China Relations in the New Decade – Konrad-Adenauer-Stiftung](https://www.kas.de/en/web/kambodscha/single-title/-/content/cambodia-china-relations-in-the-new-decade-2)). Recent meetings, such as the April 21, 2024, bilateral meeting between Cambodian Deputy Prime Minister SOK Chenda Sophea and Chinese Foreign Minister WANG Yi, reaffirmed their “iron-clad friendship” and robust political trust ([Cambodia and China Highly Value the Strong Development of Bilateral Relations – MFAIC](https://www.mfaic.gov.kh/posts/2024-04-22-News-Cambodia-and-China-Highly-Value-the-Strong-Development-of-Bilateral-Relations-in-all-Sectors-09-12-37)). Recent Developments and Projects Recent developments further illustrate the depth of this partnership. On August 5, 2024, the groundbreaking ceremony for the China-funded Funan Techo Canal Logistics System Project in Kandal province highlighted China’s commitment to enhancing Cambodia’s infrastructure, with an estimated cost of $1.7 billion ([Why Is China Investing In a $1.7 Billion Canal in Cambodia? – CFR](https://www.cfr.org/blog/why-china-investing-17-billion-canal-cambodia)). This project, part of China’s broader vision to influence ASEAN and international trade, aims to divert trade routes and boost regional connectivity, potentially impacting neighboring countries like Vietnam and Thailand. ### Related**Posts** ### 󠀁[How China’s Innovation Drives the Transformation of Thailand’s Economy](https://www.thailand-business-news.com/china/325721-how-chinas-innovation-drives-the-transformation-of-thailands-economy)󠁿 ### 󠀁[Thailand is rolling out a new EV tax structure linked to local manufacturing](https://www.thailand-business-news.com/asean/329565-thailand-is-rolling-out-a-new-ev-tax-structure-linked-to-local-manufacturing)󠁿 ### 󠀁[China and ASEAN trade deal speeds up business exchanges](https://www.thailand-business-news.com/asean/329080-china-and-asean-trade-deal-speeds-up-business-exchanges)󠁿 ### 󠀁[TAT is expanding Nihao Month 2026 to boost travel to China and increase engagement](https://www.thailand-business-news.com/china/328558-tat-is-expanding-nihao-month-2026-to-boost-travel-to-china-and-increase-engagement)󠁿 High-level visits continue to strengthen ties, with Cambodian Prime Minister Hun Manet choosing China as his first foreign destination in September 2023 and attending the 3rd Belt and Road Forum in October 2023 ([Cambodia’s Outreach to the West Does Not Change China’s Centrality – Fulcrum](https://fulcrum.sg/cambodias-outreach-to-the-west-does-not-change-chinas-centrality/)). Even former Prime Minister Hun Sen, despite stepping down, maintains “strategic communication” with Beijing, attending the Boao Forum in March 2024, reflecting China’s recognition of his influence ([Cambodia’s Outreach to the West Does Not Change China’s Centrality – Fulcrum](https://fulcrum.sg/cambodias-outreach-to-the-west-does-not-change-chinas-centrality/)). Comparative Context: Other Allies While China dominates, Cambodia’s foreign policy is not exclusively China-centric. Historical ties with Russia, another “old friend,” date back to 1956, with significant Soviet support during the Cold War, including the construction of the Khmer-Soviet Friendship Hospital and Institute of Technology ([65 years of Cambodia-Russia relations: An overview – Phnom Penh Post](https://www.phnompenhpost.com/opinion/65-years-cambodia-russia-relations-overview)). However, current economic relations with Russia are less robust, with two-way trade totaling $94.18 million in 2021 and stagnant investment, compared to China’s extensive engagement ([How Is Cambodia Navigating the Impacts of Russia’s Invasion of Ukraine? – The Diplomat](https://thediplomat.com/2022/03/how-is-cambodia-navigating-the-impacts-of-russias-invasion-of-ukraine/)). Relations with Russia soured in March 2022 following Cambodia’s condemnation of Russia’s invasion of Ukraine, contrasting with its consistent alignment with China( [Cambodia–Russia relations – Wikipedia](https://en.wikipedia.org/wiki/Cambodia%E2%80%93Russia_relations)). The United States and Western nations have also engaged Cambodia, with recent efforts to repair relations under Prime Minister Hun Manet, but these are often overshadowed by human rights concerns and sanctions, driving Phnom Penh closer to Beijing ([Embracing China, new Cambodian PM approached by US – VOA](https://www.voanews.com/a/embracing-china-new-cambodian-pm-approached-by-us-/7554083.html)). Cambodia’s diversified foreign policy, including outreach to Japan and Europe, does not diminish China’s centrality, as evidenced by its consistent backing of Beijing’s interests ([Cambodia Has Not Tilted Away from China – Fulcrum](https://fulcrum.sg/cambodia-has-not-tilted-away-from-china/)). Challenges and Public Perception Despite the strong partnership, challenges exist, particularly in public perception. China’s elite-centric approach, focusing on infrastructure and BRI projects, has raised concerns about transparency, environmental impact, and social issues, such as the proliferation of online gambling ([Lost in translation: China’s elite-centric approach in Cambodia – Lowy Institute](https://www.lowyinstitute.org/the-interpreter/lost-translation-china-s-elite-centric-approach-cambodia)). A survey in Phnom Penh and 11 provinces revealed ambivalent views, with some Cambodians questioning whether these projects align with their interests, potentially tarnishing China’s image among ordinary citizens ([Lost in translation: China’s elite-centric approach in Cambodia – Lowy Institute](https://www.lowyinstitute.org/the-interpreter/lost-translation-china-s-elite-centric-approach-cambodia)). Table: Key Metrics of China-Cambodia Relations | Metric | Details | | Historical Ties | Dating back to Tang Dynasty, with trade and cultural exchanges since 7th century | | Chinese Population in Cambodia | Approximately 950,000, 3-5% of population, prominent business community | | Trade (2021) | China is largest trading partner, bilateral trade significant | | Investment (2021) | $2.32 billion, up 67% year-on-year, largest investor | | Aid (by 2017) | $4.2 billion in grants and soft loans | | Recent Projects | Funan Techo Canal ($1.7 billion), BRI infrastructure (roads, bridges, ports) | | Political Status | Comprehensive strategic partnership since 2010, “iron-clad” friendship | Conclusion China’s role as Cambodia’s “big old friend” is well-supported by historical ties, current economic dominance, and political alignment. While challenges in public perception and environmental concerns exist, recent developments like the Funan Techo Canal and high-level engagements reaffirm their partnership. This relationship, while not without complexities, remains a cornerstone of Cambodia’s foreign policy, distinguishing it from other allies like Russia, whose influence has waned in comparison. --- Key Citations * [Cambodia–China relations historical overview](https://en.wikipedia.org/wiki/Cambodia%E2%80%93China_relations) * [Lost in translation China’s elite-centric approach in Cambodia](https://www.lowyinstitute.org/the-interpreter/lost-translation-china-s-elite-centric-approach-cambodia) * [How Small States Navigate U.S.-China Rivalry case of Cambodia](https://www.usip.org/publications/2023/09/how-small-states-navigate-us-china-rivalry-case-cambodia) * [Cambodia’s Outreach to the West Does Not Change China’s Centrality](https://fulcrum.sg/cambodias-outreach-to-the-west-does-not-change-chinas-centrality/) * [Cambodia Has Not Tilted Away from China analysis](https://fulcrum.sg/cambodia-has-not-tilted-away-from-china/) * [Cambodia-China friendship unbreakable economic ties](https://en.ndrc.gov.cn/news/mediarusources/202211/t20221107_1340948.html) * [Cambodia and China Highly Value Bilateral Relations development](https://www.mfaic.gov.kh/posts/2024-04-22-News-Cambodia-and-China-Highly-Value-the-Strong-Development-of-Bilateral-Relations-in-all-Sectors-09-12-37) * [Why Is China Investing In a $1.7 Billion Canal in Cambodia?](https://www.cfr.org/blog/why-china-investing-17-billion-canal-cambodia) * [65 years of Cambodia-Russia relations historical overview](https://www.phnompenhpost.com/opinion/65-years-cambodia-russia-relations-overview) * [How Is Cambodia Navigating the Impacts of Russia’s Invasion of Ukraine?](https://thediplomat.com/2022/03/how-is-cambodia-navigating-the-impacts-of-russias-invasion-of-ukraine/) * [Embracing China, new Cambodian PM approached by US diplomatic efforts](https://www.voanews.com/a/embracing-china-new-cambodian-pm-approached-by-us-/7554083.html) * [Cambodia–Russia relations historical and current dynamics](https://en.wikipedia.org/wiki/Cambodia%E2%80%93Russia_relations)
