As tensions flared along the Thailand-Cambodia border once again, Chinese President Xi Jinping urged both sides to exercise restraint and resolve their differences through dialogue. The appeal was ofcourse unsurprising; over the past few years, Beijing has increasingly cast itself as a champion of political settlement, presenting Chinese diplomacy as a responsible alternative to what it portrays as the militarised and interventionist approaches of the West. From brokering the restoration of diplomatic ties between Saudi Arabia and Iran to releasing peace proposals on Ukraine and hosting reconciliation talks among Palestinian factions, China has sought to project the image of a rising power capable of delivering stability in an increasingly fractured international order.
China’s emergence as a diplomatic actor reflects a broader shift in its foreign policy. Under Xi Jinping, Beijing no longer sees itself merely as an economic power or a participant in global governance. It increasingly seeks recognition as a provider of global public goods, including conflict mediation. The Global Security Initiative (GSI), unveiled in 2022, embodies this ambition by advocating “indivisible security”, dialogue over confrontation and respect for sovereignty as the foundations of international peace. Yet behind this rhetoric lies a more fundamental objective of strengthening China’s claim to leadership within an evolving international order.
There is in itself however, is a widening gap between Beijing’s diplomatic narrative and its mediation record. China has become increasingly visible in peace diplomacy but considerably less successful in producing durable political settlements. The problem is not an absence of diplomatic engagement, but the character of that engagement. Beijing often appears more interested in being recognised as a mediator than in assuming the political costs that successful mediation inevitably demands. It has demonstrated an ability to convene dialogue, but far less willingness to pressure parties, enforce compromises or remain invested once negotiations become politically costly.
The Saudi-Iran rapprochement remains China’s signature diplomatic achievement. In March 2023, Beijing hosted negotiations that restored diplomatic relations between the two regional rivals after seven years of estrangement. The agreement was widely celebrated as evidence that China could achieve what years of Western diplomacy had not. For Beijing, it reinforced its credentials as a credible diplomatic actor in the Middle East and demonstrated that its growing economic influence could translate into political capital.
Yet the agreement also exposed the limits of China’s approach. Restoring embassies was never synonymous with resolving the strategic rivalry that has fuelled conflicts across Yemen, Syria and Lebanon for more than a decade. Diplomatic communication resumed, but the underlying competition persisted. Beijing facilitated détente rather than reconciliation-an important diplomatic opening, but one that left the structural drivers of regional instability largely untouched. The episode illustrated China’s preference for brokering symbolic breakthroughs while avoiding the far more difficult task of sustaining political settlements.
Myanmar offers perhaps the clearest illustration of Beijing’s contradictory role. Since the military coup in 2021, China has simultaneously maintained relations with the junta, engaged ethnic armed organisations operating along its border and coordinated with neighbouring governments seeking to contain the conflict. Beijing has periodically facilitated ceasefires, particularly in northern Myanmar, where fighting threatens Chinese investments and border security. Yet these arrangements have repeatedly collapsed because they address the immediate symptoms of instability rather than the political drivers of the conflict.
Stability along its southwestern frontier and the protection of projects linked to the China-Myanmar Economic Corridor have consistently taken precedence over an inclusive political settlement. China’s diplomacy has therefore functioned less as conflict resolution than as conflict management, seeking to prevent instability from spilling across its borders rather than addressing the conditions that perpetuate violence.
A similar pattern was evident in Ukraine where since Russia’s military operations in 2022, China has consistently portrayed itself as an advocate of peace. It released a twelve-point position paper, opposed the use of nuclear weapons and later partnered with Brazil to promote a broader peace initiative. Yet Beijing has remained unwilling to exert meaningful pressure on Moscow, arguably the one actor over which it possesses genuine leverage. This reluctance has inevitably undermined perceptions of China’s neutrality. Effective mediators are often required to challenge the behaviour of their closest partners; Beijing has instead prioritised preserving its strategic relationship with Russia while simultaneously presenting itself as an impartial broker.
The Middle East provides another example where China has repeatedly called for ceasefires in Gaza, supported a two-state solution and hosted reconciliation talks among Palestinian factions. These initiatives have strengthened Beijing’s diplomatic profile, particularly across the Global South, but have produced limited influence over developments on the ground. China has shown little inclination to invest the sustained diplomatic capital required to move beyond symbolic engagement, reinforcing the perception that visibility often takes precedence over effectiveness.
Xi Jinping’s recent appeal for restraint between Thailand and Cambodia follows the same pattern. Both countries occupy important positions within China’s economic and strategic engagement in mainland Southeast Asia, and instability threatens infrastructure projects, trade corridors and Beijing’s broader regional ambitions. China has therefore encouraged dialogue while carefully avoiding a role that would require sustained political commitment or risk alienating either partner. Once again, Beijing has preferred to remain an acceptable interlocutor rather than an accountable mediator.
This caution stems in part from the principles that China has long championed. Sovereignty and non-interference remain central pillars of Beijing’s foreign policy and have earned it considerable goodwill among developing countries wary of external intervention. Yet these same principles also constrain China’s ability to mediate effectively. Durable peace agreements often require mediators to pressure allies, propose politically uncomfortable compromises and, where necessary, underwrite agreements through monitoring mechanisms or long-term security commitments. Beijing has consistently resisted such responsibilities, preferring to facilitate negotiations without becoming responsible for their success or failure.
The latest tensions between Thailand and Cambodia therefore illustrate more than another regional dispute. They underscore the evolution of China’s diplomacy from passive observer to active diplomatic stakeholder. Yet they also expose the limitations of a mediation model that privileges influence over resolution and visibility over responsibility. As Beijing’s global footprint continues to expand, so too will expectations that it moves beyond facilitating conversations to assuming the burdens of sustaining peace.
