China and Cambodia Vow Deeper Unity as Belt‑and‑Road Ties and Political Cooperation Accelerate

The most recent articulation of this sentiment came during a meeting between Chinese President Xi Jinping and Cambodian Prime Minister Hun Sen, an encounter that underscored a shared narrative of mutual support on “core issues of national sovereignty, security and territorial integrity.” In a joint communiqué dated 13 September 2022, both leaders affirmed their respect for each other’s development models and pledged to continue “welcoming each other’s national development and revitalisation efforts.” The language was more than diplomatic nicety; it was a clear signal to the international community that any attempt to sow discord between the two neighbours would be met with a united front.

Economic cooperation lies at the heart of the partnership. Since Cambodia’s accession to China’s Belt and Road Initiative (BRI), the country has seen a surge in infrastructure projects – most notably a network of expressways that have turned a once‑isolated nation into a more connected hub in the Mekong sub‑region. Chinese‑funded roads, bridges and energy plants are now integral to Cambodia’s growth strategy, and Cambodian officials regularly credit the BRI with “transforming” their economy. The visible fruits of this cooperation have been highlighted in recent Chinese media reports, although a systematic analysis of public sentiment on platforms such as Weibo is surprisingly scarce. What appears clear is that the official narrative – emphasising “win‑win” outcomes and “mutual prosperity” – dominates the discourse.

Beyond bricks and mortar, the two nations have also aligned themselves against external interference. A December 9 2021 statement from Beijing’s foreign ministry reiterated China’s readiness to “stand with the Cambodian people” in safeguarding their “national sovereignty and dignity,” condemning any foreign attempts to destabilise the bilateral relationship. This stance is mirrored in Phnom Penh’s diplomatic posture, where Cambodia has consistently voted alongside China on contentious issues within the United Nations, ranging from South‑China Sea disputes to calls for reforms in the global trade regime.

The partnership’s depth is rooted in a historical trajectory that stretches back to the 1950s, when China first recognised Cambodia’s independence and provided crucial assistance during periods of internal upheaval. Over the decades, Beijing’s approach has evolved from ideological solidarity to a more pragmatic model of “strategic trust and cooperation,” as Chinese officials describe it. The emphasis now lies on “dialogue, partnership, and stable, balanced development of relations with major powers,” a phrasing that seeks to reassure neighbouring states while still positioning China as the leading architect of a “friendly and coexisting Asian home.”

Regional initiatives further cement the alliance. Both countries are active members of the Lancang‑Mekong Cooperation (LMC) mechanism, a China‑led forum that brings together five Southeast Asian nations to address water management, environmental protection and cross‑border trade. Participation in the LMC underscores a shared commitment to regional stability and development, while also providing a platform for joint projects that dovetail with the BRI’s broader objectives.

Key figures beyond Xi Jinping and Hun — including ambassadors, trade ministers and senior officials from the China‑ASEAN Center — are instrumental in turning high‑level rhetoric into concrete agreements. For example, Chen Dehai, secretary‑general of the China‑ASEAN Center, has frequently spoken at forums in Phnom Penh, outlining collaborative pathways in digital economies, cultural exchange and intellectual property protection. Their work, though less visible to the public eye, translates the lofty language of “standing together more firmly” into joint ventures, scholarships and shared research initiatives.

While the official narrative is both robust and consistently optimistic, the lack of comprehensive public‑opinion data means it is difficult to gauge how ordinary Cambodians or Chinese citizens feel about the deepening ties. Social‑media scans have uncovered a handful of supportive posts praising infrastructure progress, but also a muted chorus of critics wary of growing dependence on Beijing. Nonetheless, the state media rhythm — celebrating mutual respect, non‑interference and “shared destiny” — suggests that any dissenting voices are being quietly managed within the broader political context.

In sum, the phrase “China and Cambodia should stand together even more resolutely” is more than a diplomatic slogan; it encapsulates a relationship that has matured into a strategic cornerstone for both capitals. Through coordinated political backing, expansive economic projects under the Belt and Road, and a joint stance against external meddling, the two nations are forging a partnership that they hope will withstand the shifting currents of global geopolitics. Whether this alliance will translate into enduring prosperity for the peoples of both countries remains to be seen, but for now, the message from Beijing and Phnom Penh is unmistakably united.
