In Brief


  • The International Organisation for Mediation (IOMed) was launched in May 2025 in Hong Kong, with 33 founding members from across the Global South and beyond.

  • IOMed aims to provide a dedicated international platform for mediation, offering an alternative to arbitration and litigation in resolving state, investor and commercial disputes.

  • While China leads the initiative, the IOMed positions itself as a neutral and inclusive forum, with over 20 international organisations welcoming its introduction.

  • Australia has not yet joined, but many of its regional neighbours have. Australian firms may still access IOMed services without state membership.

  • The IOMed could offer strategic value for Australia, particularly in managing complex disputes such as the Port of Darwin lease.

  • This article explores whether Australia should consider joining, and what role it could play in shaping the IOMed’s development.


In May, a Chinese-led ceremony in Hong Kong launched the International Organisation for Mediation (IOMed), a new legal body that seeks greater use of mediation in dispute resolution. As a new international organisation that will add to the already existing institutions of international law, the IOMed is structured to address a broad range of disputes – including those involving private entities, commercial entities, international organisations and sovereign states. 

The establishment of the IOMed represents a growing collection of Asia-based international bodies that function both as alternatives to and complements of their Western-based counterparts. This inevitably raises the question: how should Australia engage with the IOMed? Before we get to that, let us examine IOMed and its approach to mediation more closely. 

Who joined and who was present at the signing ceremony?

Even though the convention was signed in May 2025, the IOMed is not expected to be operational until the end of the year. The 33 founding members come from Asia, Latin America, the Pacific, Africa and Europe. Notably, some of these founding members are Australia’s closest neighbours including Indonesia, East Timor, Papua New Guinea, Kiribati and Nauru. State members will hold a key role in shaping the IOMed. As noted in the Convention on the Establishment of the International Organisation for Mediation, the Governing Council of the IOMed will establish the policies and strategies of the mediation body. It will be composed of state members, referred to as ‘Contracting States’ – initially the 33 founding members, with the possibility of expanding to include additional signatories over time. The Governing Council will seek consensus on decisions but will resort to simple majorities if consensus cannot be reached.

The signing ceremony was attended by representatives from over 80 states and 20 international organisations, including delegates from the United Nations (UN) and the International Committee of the Red Cross (ICRC). UN representative Junhua Li spoke at the ceremony, noting, “The UN stands ready to partner closely with the IOMed, leveraging our respective strengths and expertise to promote mediation at all levels.” Meanwhile, Boris Kelecevic of the ICRC focused on the conflict resolution potential of the IOMed, stating, “The establishment of the International Organisation for Mediation may offer hope, as there may be a forum where armed conflicts could end through mediation, or humanitarian agreements might be brokered to alleviate human suffering during armed conflict and violence.”


The IOMed’s structure, scope and strategic role

The establishment of the IOMed has been in the works for a few years. In 2022, a small group of state parties presented a Joint Statement on the formation of the IOMed. The 2023 Hong Kong Mediation Lecture presented by Dr. Sun Jin, outlined the necessity, progress, scope and function of the IOMed. Interestingly, it also included a discussion on enforcement (see below) and the kinds of cases that would be included. Dr. Sun Jin mentioned in his speech that to distinguish the IOMed from adjudicative and arbitral bodies, the convention avoids the use of the term “jurisdiction”.  Instead, the mediation process is entirely voluntary with outcomes reached through mutual agreement. Notably, the IOMed will provide mediation services not limited to states. Mediation facilities will include disputes between states, commercial and investor disputes between a state and a national of another state, and international commercial disputes between two or more firms.

The IOMed presents itself as an “impartial, neutral and equitable environment” for global actors to seek mutually beneficial outcomes on disputes. Headquartered in Hong Kong, the IOMed is open to membership for all states and regional organisations. Although it has been reported that China hopes that the IOMed will rival the International Court of Justice (ICJ) in dispute resolution, it will essentially function as a complementary international legal body that will add to the existing collective of international legal organisations associated with mediation, such as the Singapore Convention on Mediation, the ICC International Court of Arbitration, International Centre for Settlement of Investor Disputes (ICSID) and the UN Commission on International Trade Law’s Working Group III’s Investor-State Dispute Settlement (ISDS) Reform. The fundamental difference is that the IOMed will be a dedicated international mediation body in all its forms – a one-stop-shop for states, international firms and international organisations.

Why choose mediation as a dispute resolution mechanism?

Mediation is a dispute resolution process where parties accept the assistance and services from an independent third party to facilitate negotiations. Unlike arbitration, mediation does not rely on legal authority to impose a decision. Instead, it seeks outcomes that all parties consent to, resulting in a mutually agreed resolution such as a legally binding agreement, protocol, joint communiqué or declaration.

Depending on how negotiations unfold, mediation can be significantly faster than an international court case or arbitration hearing. According to the International Chamber of Commerce (ICC), the average duration of a court case was 27 months. Conversely, the average duration of mediation is less than four months.

International organisations like the United Nations and the European Union have spent decades bolstering their capacity in mediation services, primarily in conflict resolution and state-to-state issues. Mediation as an effective alternative to arbitration has grown significantly of late and has been adopted widely. For instance, mediation facilities have been embedded in international agreements such as the ASEAN Comprehensive Investment Agreement (ACIA), Indonesia-Australia Comprehensive Economic Partnership Agreement (IA-CEPA) and the Regional Comprehensive Economic Partnership Agreement (RCEP). The Singapore Convention on Mediation represents the United Nation’s efforts to establish mechanisms to enforce mediation settlement agreements for international trade.

Mediation is increasingly becoming the preferred method of dispute resolution as it works towards an amicable outcome that is mutually beneficial. Unlike arbitration, mediation avoids the binary outcome in which one party is rewarded to the detriment of the other. Instead, it provides a platform for negotiation, allowing the parties come to an agreement that is either mutually satisfying or, at the very least, mutually tolerable. As China’s Foreign Minister, Wang Yi, noted, “The establishment of the International Organisation for Mediation helps to move beyond the zero-sum mindset of 'you lose and I win'”. From this perspective, the Chinese government and the IOMed are seeking to promote the organisation as a productive alternative that empowers all parties to negotiate better outcomes for themselves.

How will the IOMed prove its worth?

To establish its credibility as an effective international body for mediation, the IOMed must demonstrate its utility in three critical ways:

  1. Mediating cases of international significance: Resolving disputes that holds international attention would provide global credibility and thereby attract other parties to use such services.

  2. Establishing a consistent track record in amicably settling cases where parties agree to binding agreements.

  3. Capacity to enforce mediated agreements: A major criticism of the Singapore Convention on Mediation is that a party could simply violate the mediated agreement without enduring a significant consequence. The other party would only have the rather unappealing option of seeking restitution through lengthy legal processes. Article 41 of the IOMed Convention includes a protocol that outlines the conditions under which the mediated agreement shall be enforced. The effectiveness of this mechanism will depend on how the mediated agreements are negotiated and structured. Once real-world examples emerge, experts will be better positioned to assess whether the IOMed has addressed the fundamental shortcomings of the Singapore Convention.

Establishing legitimacy will take time. The IOMed’s progress should be monitored closely and critically assessed.

Why has the West remained absent from the IOMed so far?

The leaders of the Western world were noticeably absent from the signing ceremony, apart from the Swiss government who made a speech as an Observer State. The response from the West in general has been rather muted. Despite efforts to obtain official statements from the United States, Australia and the European Union, none had been forthcoming at the time of the article’s publication.

The establishment of the IOMed has been led by China, with a specific focus on improving the opportunities for the Global South to have a fair hearing in an international legal system traditionally dominated by the West. A representative from Hong Kong noted that the IOMed “features a higher representation from the Global South and developing countries, filling a longstanding gap in the international dispute resolution landscape”. This will be especially evident in the Governing Council, where the Global South will have a leading role in shaping the IOMed into the future. Considering the amount of investment China has undertaken in Global South countries – especially through projects like the Belt and Road Initiative (BRI) – establishing an international mediation body is a logical step toward managing international commercial and investor disputes.

Some legal experts from the West have been quite sceptical of the IOMed. Julian Ku, a law professor from Hofstra University, argued that the IOMed is nothing more than a “global PR push to make it seem like China is offering a different way to resolve global disputes” without actually developing an institution of substance. Others see the IOMed as an example of China pursuing global leadership through an alternative or parallel international organisation. Regardless, the West will be watching the IOMed closely to see if it will evolve into a widely used forum for international mediation, especially in commercial and diplomatic disputes.

Should Australia join the IOMed?

Like its Western counterparts, Australia has so far not expressed any intention to join the IOMed. However, Australia’s signing of the Singapore Convention on Mediation under the Morrison government indicates a willingness to engage with international mediation frameworks. Furthermore, Australia has demonstrated pragmatism by participating in international initiatives where China is a central actor, including the Asian Infrastructure Investment Bank (AIIB) – despite vocal U.S. opposition – and the Regional Comprehensive Economic Partnership (RCEP).

For now, the Australian government seems to be taking a cautious "wait and see" approach. The IOMed is still in its formative stages and there are numerous other outlets for mediation services through platforms such as the Singapore Convention or in ad hoc forms through international organisations like the United Nations. The processes, rules and frameworks established by the IOMed through the Governing Council and capacity building efforts, combined with an examination of the processes and outcomes of its initial cases will help determine whether joining is worthwhile. As an open and voluntary international body, the IOMed does not require Australia to become a member in order to access its mediation services, as noted in Article 25 of the Convention. However, if Australia were to use mediation services as a Non-Contracting State, it would be “subject to such rules as may be adopted by the Governing Council,” which could limit Australia’s negotiating options.

If Australia were to join, it would gain a seat on the Governing Council, allowing it to play a significant role in shaping the mediation processes and rules within IOMed. If Australia joins after the IOMed has been fully established, it will miss the opportunity to influence its structural and operational foundations. Given that Australia’s largest trading partner and many of its closest neighbours are members of the IOMed, their participation may serve as a useful reference point when assessing the potential relevance of Australia’s own membership. It should be noted that Australian firms could voluntarily choose to participate in mediation within the IOMed framework without Australia being a formal member (Article 27). However, an Australian presence on the Governing Council could offer indirect benefits to firms engaging with the IOMed.

The Port of Darwin: A potential test case?

The IOMed presents possible opportunities for the Australian government to achieve amicable and stable outcomes through mediation with China and other neighbouring states.  For instance, the IOMed could serve as a platform to facilitate negotiations over the termination of the 99-year lease of the Port of Darwin to the Chinese-owned Landbridge Group.

The Australian government does have disinvestment powers based on national security grounds or if the Port of Darwin is deemed as critical infrastructure. However, Landbridge could make such a process quite difficult through the terms of its lease agreement and protections under the China-Australia Bilateral Treaty (CABIT) and China-Australia Free Trade Agreement (ChAFTA), potentially triggering investor–state dispute settlement (ISDS) arbitration. Such a process would not only prolong the process towards the end-goal of divestment, but it also has the real possibility of significantly damaging relations with China.

Engaging in a mediation process has the potential for mutually beneficial outcomes for all parties – Australia regains control of the Port of Darwin and China’s new mediation initiative gains international legitimacy through a successful mediation case involving a noteworthy state actor. If the Albanese government encounters increasing resistance from Landbridge over relinquishing the port, mediation could become an attractive and pragmatic option.  

Conclusion

The global scope and legitimacy of the International Organisation for Mediation (IOMed) will be determined by its ability to deliver impartial and effective outcomes for all parties involved in its processes. Achieving this will require expanding its membership and attracting participation from a diverse range of global actors, including international firms and organisations.

For Australia, the government will need to carefully consider both the opportunities and challenges that IOMed presents. Although Australia has not yet expressed interest in joining, early membership could offer the government a chance to shape norms, rules and procedures by taking an active role in the Governing Council. With many of Australia’s regional neighbours as founding members and China assuming a leading role, Australia’s stance on IOMed will serve as an interesting measure on how it seeks to engage with the global shifts currently unfolding.
