Cambodia-China relations date back to not less than two thousand years; however, these relations precisely appeared at the meeting between Samdech Norodom Sihanouk, Head of State of the Kingdom of Cambodia, and Zhou Enlai, Prime Minister of the People’s Republic of China in the Afro-Asian Conference in Bandung in 1955. In 1956 Samdech Norodom Sihanouk visited Beijing to sign a declaration of friendship between Cambodia and China. Starting from that declaration, Cambodia officially established diplomatic relations with the People’s Republic of China on 19 July 1958.In the joint declaration, the two countries expressed goodwill to abide by the five-pacific co-existence principles as a guideline for relations between the two countries. The two heads of states clearly understood that the relations between the two countries not only conformed to the interests of the two nations but also to the whole world.Both governments tried to bring about friendship, mutual respect and trust, and better cooperation. Heads of governments of the two countries vowed to fully abide by the decision of the Bandung Conference to facilitate and enhance communication between nations and to eliminate mutual distrust between the nations in the region.Despite a long-distance, different languages, and different political regimes, Cambodia and China share smiles, drink the same source of water, the Mekong and Lancang river, consume oxygen, and have a common goal in building good relations with each other. No matter what the circumstances are, China always pays attention to its relations with Cambodia by providing support to Cambodia to walk on a development pathway that suits its own condition.In April 2006, China and Cambodia agreed to raise their bilateral relations to a comprehensive partnership of cooperation and upgraded to a comprehensive strategic partnership in 2010. Moreover, the two countries also signed “Action Plan 2019-2023 on Building China-Cambodia Community of Shared Future” in April 2019.Recently, Cambodia and China do enjoy very strong political, military, economic, and socio-cultural cooperation. The investment and trade volume has grown remarkably. This trend greatly contributes to the governments of both countries in the efforts in strengthening and broadening the relations and cooperation between the two countries, and it has also significantly contributed better mutual understanding between Cambodian and Chinese people on their past and present history; moreover, it conveys a message of peace, friendship, development, and cooperation between the two countries and peoples to a higher level.The relations between the two countries are now at the best stage and the highest level ever, and they are more comprehensive and strategic ones. China is Cambodia’s big supporter in socio-economic development. Cambodia and China are good brothers, neighbors, and partners, and the two countries always provide mutual supports and cooperate with each other very well.State and high-level visits have been made by leaders of both countries. Cooperation and mutual supports in international and regional affairs between the two are getting closer and bigger day by day. Based on high-level political consensus, the two countries have mutual understanding, respect, and support for each other, and they jointly maintain the good situation of China-ASEAN relations as well as regional peace and security. Cambodia has always been at the forefront of the pragmatic cooperation between China and other ASEAN countries.As China is conducting cooperation on production capacity with developing countries, including ASEAN countries, Cambodia is an active participant in the process and has signed the MOU. China and Cambodia are also good partners under the ASEAN Plus China framework, such as the negotiation on an upgraded FTA, the Regional Comprehensive Economic Partnership negotiation, and the newly launched Lancang-Mekong Cooperation.Cambodia is one of the most supportive of the Belt and Road Initiative (BRI) due to the fact that economic opportunities generated from the initiative are believed to be tremendous. Both countries are at different stages of development and have complements for each other; their political relationship at the highest level is excellent, and both countries are politically stable and peaceful. Politically, Cambodia is one of China’s oldest and closest friends. Economically, China is Cambodia’s top foreign investor, a major donor, and an increasingly important trading partner. Culturally, Chinese values are deeply embedded in many aspects of Cambodian society.Under the Cambodia-China BRI cooperation, China has invested in many large projects in Cambodia. The development of infrastructures, such as roads, rails, airports, seaports, hydropower plants, and special economic or industrial zones, is an example of the benefit of BRI cooperation in Cambodia. BRI has a very positive impact on Cambodian economic growth. This initiative not only brings enormous advantages to the countries involved, but also becomes a long-term strategy to promote connectivity and cooperation in all fields such as infrastructure, economy, investment, and finance, as well as strengthens people-to-people bonds.Exchange programmes have been conducted in the areas of culture, government officials, media, youth, and academics with the funding support of the Chinese government. In terms of trade, tourism, and educational and cultural exchanges, the relations of the two countries have reached a new peak. The influx of Chinese businesses and people has contributed greatly to Cambodia’s development and shares in GDP.Cambodia has also become a key tourist destination to attract a large number of Chinese tourists. Chinese tourists flowing into Cambodia have been increased through the “China Ready Policy.” However, according to the statistics of the Ministry of Tourism in 2018, Chines e tourists who came to Cambodia amounted to over 2 million people, and within a 9-month period in 2019, 1.864.956 Chinese tourists visited Cambodia, which’s an unexpected number.Tourism is now playing a very important role not only for economic benefit and generating jobs but also for promoting Cambodian rich and colorful culture and civilization; at the meantime, heritage protection is equally important to promote the tourism sector. Through tourism and heritage protection, Chinese and Cambodian people can exchange and mutually learn about their civilizations.Chinese tourists range number one in the Cambodian tourism sector. Chinese tourists and investment are key to the future of Cambodia’s tourism industry. Cambodia understands this trend clearly and is ready to welcome Chinese tourists and investors, especially by facilitating hospitality, encouraging visitors, and providing a welcoming investment environment to China as a great friend of Cambodia.The relations between Cambodia and China have become a model of friendly coexistence and close cooperation among countries. Just as President Xi Jinping has reiterated that China and Cambodia are friendly neighbors and brothers and this has been always reaffirmed by Cambodian leaders. The two countries cherish the traditional friendship that has withstood the test of time and changes in the international situation.Samdech Akka Moha Sena Padei Techo Hun Sen, Prime Minister of the Kingdom of Cambodia, attached great importance of Cambodia-China relations. With wisdom and a far-sighted vision, Samdech has affirmed the essential existence of Cambodia-China relations in political, economic, and socio-cultural contexts. Samdech realizes that Cambodia cannot isolate herself, and she cannot lack partners in development. The important point is that the friendly relations between Cambodia and China are based on the principles of equal footing with equal rights, respect for sovereignty, and mutual benefit and assistance. As a matter of fact, Samdech’s Win-Win Policy has provided Cambodia a full peace, and other foreign countries, especially China put the trust in Samdech.In his message, His Excellency Xi Jinping, President of the People’s Republic of China, to the people of Cambodia in October 2016, prior to his official visit, he emphasized that Cambodia was an important link on the Maritime Silk Road. Cambodia is well known for its rich history and the unique Khmer culture. The Angkor Wat, with its magnificent architecture and stunning bas-reliefs, stands as a true tribute to the talent of the Cambodian people and shines in the annals of human civilization. Entering the 21st century, Cambodia has made much progress in development and delivered a better life to its people. It is heading towards a promising future.Facing such a situation, Cambodia, a brave nation, must ultimately struggle for its existence in the present and for the next generations as well. Cambodians have to think of opportunities for competition and future vision and have to begin solving with other nations as well. Strengthening and expanding its existence with other nations for peaceful cooperation and mutual benefits is absolutely a significant factor.“A friend in need is a friend indeed” is a slogan which is true and virtuous. China, a good friend of Cambodia, has always helped Cambodia, and the Kingdom of Cambodia has fully and unwaveringly supported the “One-China” Policy principle. Cambodia and China are friends with a long history of relationship dating back to the visit of Zhou Ying and Kaing Thai to Cambodia in the Funan period, which is historically not less than the last 2,000 years.In sum, the key points of Cambodia-China relations are prioritized by the Cambodian government because China always sticks with the principle of non-interference. Cambodia-China relations have reached the best stage and highest level ever in history, from good neighbor relations to a comprehensive and strategic partnership of cooperation and mutual trust and assistance. The Cambodia-China relations are the key paradigm of cooperation for other nations in the region and the world.
