Cambodia and Myanmar have agreed to deepen cooperation across trade, investment, tourism, security, education and other strategic areas as their leaders seek stronger ties at bilateral, regional and global levels. The commitment was reaffirmed during talks between Cambodian Prime Minister Samdech Moha Borvor Thipadei Hun Manet and Myanmar President U Min Aung Hlaing at the Peace Palace in Phnom Penh on September 11, 2026, during the Myanmar president’s two day state visit to Cambodia.
The meeting produced a particularly important outcome for the private sector. Following their discussions, the two leaders witnessed the signing of four cooperation documents covering the elimination of double taxation, reciprocal investment promotion and protection, cultural cooperation, and media and information cooperation. The agreements come as both governments also look to strengthen cooperation against transnational crime, including human trafficking, drug trafficking and cybercrime.
“Cambodia and Myanmar are giving their longstanding relationship a broader economic and strategic framework, with new agreements designed to make investment more predictable, strengthen cultural and media links, and support closer cooperation against transnational crime. The four documents signed in Phnom Penh address double taxation, investment protection, cultural cooperation, and media and information cooperation. At the same time, the two governments are looking to expand cooperation in trade, tourism, education, security and technology related scams. The economic relationship still has considerable room to grow. Myanmar’s exports to Cambodia were valued at US$23.07 million in 2025, according to United Nations COMTRADE data reported by Trading Economics, with tobacco and tobacco products accounting for US$22.52 million. The new agreements could therefore be viewed as part of a broader effort to build the policy framework needed for deeper commercial engagement.”
Leaders Signal a Broader Cambodia Myanmar Partnership
Prime Minister Hun Manet welcomed President U Min Aung Hlaing and his delegation during the meeting at the Peace Palace, describing the visit as a reflection of the longstanding friendship, relations and cooperation between Cambodia and Myanmar. The Myanmar president expressed appreciation for the hospitality provided by the Cambodian government and people during his state visit.
U Min Aung Hlaing also highlighted Cambodia’s development and modernisation, noting that his first state visit to Cambodia as president gave him an opportunity to observe the country’s transformation compared with his previous visit in 2017. He described Cambodia as a good and close friend and highlighted Cambodia’s support for Myanmar within ASEAN and international frameworks, particularly during Cambodia’s ASEAN chairmanship in 2022.
The diplomatic message is significant because the relationship is being discussed across several areas at once. Rather than limiting cooperation to traditional government relations, the two sides are linking economic development with tourism, education, security, investment and regional cooperation.
Four Agreements Put Trade and Investment in Focus
The most commercially relevant outcome was the signing of four cooperation documents. The first is an agreement on the elimination of double taxation and prevention of tax evasion and avoidance. The second covers reciprocal promotion and protection of investments. The third concerns cultural cooperation, while the fourth is a memorandum of understanding on media and information cooperation.
For companies and investors, the tax agreement and investment protection agreement are particularly important. Double taxation can increase the cost and complexity of cross border business, while uncertainty over investment protection can affect decisions about entering a foreign market. Establishing formal agreements in these areas can provide a clearer institutional foundation for businesses considering opportunities between Cambodia and Myanmar. The actual commercial impact, however, will depend on implementation and the ability of businesses to make practical use of the new frameworks.
2025 Trade Shows Significant Room for Growth
The existing trade relationship suggests that Cambodia and Myanmar still have substantial space to expand commercial exchanges. According to Trading Economics, using United Nations COMTRADE data, Myanmar exported US$23.07 million worth of goods to Cambodia in 2025. Tobacco and manufactured tobacco substitutes represented US$22.52 million of that amount, while other recorded categories included plastics, raw hides and leather, cereals, apparel, pharmaceutical products and vegetables.
The figures show that Myanmar’s exports to Cambodia remain relatively concentrated, with tobacco products accounting for the overwhelming majority of the recorded value. At the same time, the presence of agricultural products, pharmaceuticals, plastics, leather and apparel indicates that trade extends beyond a single product category. It is important to note that the US$23.07 million figure represents Myanmar’s exports to Cambodia, rather than the total bilateral trade value between the two countries. The available Trading Economics page does not provide a matching 2025 Cambodia export figure in the same dataset.
For context, Cambodia’s overall international trade was much larger in 2025, exceeding US$64 billion according to Cambodian customs data. This comparison underlines the relatively modest scale of Cambodia Myanmar merchandise trade and, at the same time, points to potential room for diversification if the new agreements help businesses identify additional products and investment opportunities.
Investment Protection Could Encourage Greater Business Confidence
The reciprocal investment promotion and protection agreement could become one of the most important components of the new cooperation package for companies. Investors typically assess not only market opportunities but also the regulatory environment, taxation, protection of assets and the predictability of cross border operations.
A formal investment framework does not automatically create investment flows, but it can help establish clearer expectations between the two countries. For Cambodian companies considering Myanmar and Myanmar businesses exploring Cambodia, stronger institutional arrangements could support discussions around market entry, partnerships and expansion. The opportunity will be particularly relevant if government agencies and private sector organisations follow the agreements with practical investment facilitation and business engagement.
Tourism and Education Are Part of the Wider Economic Agenda
The two leaders also discussed tourism, education and human resource training alongside trade and investment. These sectors can complement economic cooperation by supporting greater movement of visitors, professionals, students and business networks between the two countries.
Tourism cooperation can create opportunities for airlines, hotels, travel companies, tour operators and destination businesses, while education and skills cooperation can contribute to stronger human capital links. For businesses, these areas matter because deeper commercial relationships often develop alongside stronger people to people connections and professional networks.
The inclusion of tourism also fits into Cambodia’s broader strategy of using regional connectivity and destination cooperation to attract visitors and expand tourism markets. Closer links with Myanmar could create additional opportunities for travel products and business partnerships, although the practical scale of those opportunities will depend on market conditions and implementation.
Cambodia and Myanmar Step Up the Fight Against Cross Border Crime
Security was another major part of the discussions. The two sides reaffirmed their commitment to cooperation against transnational crime and specifically agreed to strengthen efforts against human trafficking, drug trafficking and cybercrime.
Technology related scams are particularly relevant to the regional business environment because cyber enabled crime can damage consumer confidence, corporate reputation and cross border commerce. Stronger cooperation between governments and law enforcement agencies can help address criminal networks that operate across national borders. For legitimate businesses, a stronger regional security environment can also support greater confidence in cross border economic activity.
Regional Cooperation Remains Central to the Relationship
Beyond bilateral matters, Cambodia and Myanmar also discussed mutual support within regional and international frameworks. ASEAN remains an important platform for both countries, and the leaders reaffirmed their interest in strengthening cooperation at regional and global levels.
Cambodia’s previous role in ASEAN, including its chairmanship in 2022, was specifically highlighted during the meeting. The latest discussions therefore place the bilateral relationship within a wider regional context, where cooperation on trade, security, tourism and transnational crime can involve not only the two governments but also broader ASEAN mechanisms.
Four Agreements Could Mark a New Commercial Chapter
The September 11 meeting produced more than another diplomatic reaffirmation. The four signed documents establish formal areas for deeper cooperation, particularly in taxation, investment, culture and media. For the private sector, the investment and tax agreements are likely to attract the greatest attention because they address practical issues affecting cross border business.
Yet the economic relationship remains relatively small compared with Cambodia’s overall international trade, while Myanmar’s exports to Cambodia in 2025 were heavily concentrated in tobacco products. The next challenge is therefore turning political commitments into broader commercial activity, more diversified trade and stronger investment links.
If the agreements are implemented effectively, they could provide a foundation for companies in both countries to explore new markets while supporting cooperation in tourism, education, security and other sectors. The bigger opportunity is not simply increasing the value of existing trade, but creating a more diversified and predictable framework for long term economic engagement.
