OPENING A NEW PHASE OF DEVELOPMENT FOR RELATIONS BETWEEN VIET NAM, Republic Of Korea, AND MONGOLIA

National Assembly (NA) President Tran Thanh Man and his spouse, together with a high-ranking Vietnamese delegation, are paying official visits to the Republic of Korea (RoK) and Mongolia from September 6 to 11, at the invitation of Speaker of the NA of the RoK Cho Jeong Sik and his spouse, and Chairman of the State Great Hural of Mongolia Sandag Byambatsogt and his spouse. These marked NA President Tran Thanh Man’s first official visits to the RoK and Mongolia, as well as the first visits by a Vietnamese National Assembly President to the RoK in five years and to Mongolia in 23 years.

National Assembly Chairman Tran Thanh Man’s working visits sought to actualise the foreign policy guidelines of the 14th National Party Congress, the Political Bureau’s Resolution No. 06-NQ/TW on implementing the 14th Congress’ foreign policy, and the Political Bureau’s Resolution No. 59-NQ/TW on international integration in the new situation. Through these visits, the aim is to generate significant momentum in Viet Nam’s relations with these nations, contribute to fostering a peaceful and stable environment, expand opportunities for development, and mobilise resources to successfully achieve the country’s development goals. As Viet Nam has continued its renewal process and entered a new era of development — seeking comprehensive, extensive, timely, and effective support from international partners, including the RoK and Mongolia — this visit underscored the high priority all parties place on deepening Viet Nam’s ties with these two nations and cultivating robust, trusting personal bonds between key leaders of Viet Nam and their counterparts in the RoK and Mongolia.

Consolidating the Viet Nam–RoK Comprehensive Strategic Partnership

In recent times, the RoK government has enacted decisive measures to revive economic growth momentum, stabilise society, foster national unity, and advance priority sectors such as artificial intelligence, biotechnology, culture, national defence, energy, and factory digitalisation. The RoK is focusing on expanding relations with nations in the Global South and strengthening substantive cooperation with the ASEAN region, including Viet Nam. President of the Republic of Korea Lee Jae Myung has repeatedly affirmed the importance he attaches to relations with Viet Nam, stressing that the RoK will be a reliable partner accompanying Viet Nam in effectively implementing its two strategic goals for 2030 and 2045.

Since establishing diplomatic relations nearly 35 years ago (December 22, 1992), Viet Nam and the RoK have become trusted partners engaged in strategic cooperation and close friends with profound mutual understanding. The elevation of their relationship to a Comprehensive Strategic Partnership in December 2022 marked a historic milestone, opening up vast opportunities for cooperation across all sectors. The Viet Nam–RoK Comprehensive Strategic Partnership has seen robust, substantive, effective, and comprehensive development across many fields. Political trust has continued to be fortified, while exchanges of delegations and high-level contacts take place regularly.

Economic cooperation continues to be a key pillar of bilateral relations, with bilateral economic cooperation mechanisms being effectively implemented. Defence and security cooperation has developed substantively through numerous specific projects and cooperation agreements. Science and technology cooperation has been identified as a new pillar of bilateral relations. Labour, cultural, tourism, and educational cooperation has expanded. People-to-people exchanges have been maintained in diverse and enriching forms. Nearly 400,000 Vietnamese people currently live, study, and work in the RoK, while more than 200,000 RoK citizens are in Viet Nam, serving as a solid bridge connecting the two countries.

Parliamentary cooperation is an important pillar of the Comprehensive Strategic Partnership between Viet Nam and the RoK. Relations between the legislative bodies of Viet Nam and the RoK have developed strongly and substantively, achieving many new results and making an important contribution to deepening bilateral relations. The two sides regularly hold talks, meetings, and exchanges of delegations of National Assembly leaders and NA committee-level officials, friendship parliamentary groups, women parliamentarians' groups, and young parliamentarians' groups; regularly exchange views and experiences, coordinate efforts to monitor and promote the effective implementation of signed agreements; and maintain close cooperation and mutual support at multilateral parliamentary forums such as IPU and AIPA, making active contributions to maintaining peace, security, and stability in the region and the world.

Viet Nam always attaches great importance to and wishes to elevate its cooperative relations with the RoK to a new level that is substantive, effective, and sustainable over the long term. Viet Nam supports the RoK’s development policies and efforts to enhance its international role and position, and is ready to leverage Viet Nam’s international role and position to help promote connectivity and dialogue and maintain peace and stability in the region. The two sides will continue to strengthen and expand cooperation between the two countries’ parliaments in line with their Comprehensive Strategic Partnership.

Parliamentary diplomacy contributes to leveraging the RoK’s strengths and development experience, creating breakthroughs in economic, trade, and investment cooperation between the two countries, and particularly enhancing the effectiveness of the new pillar of science and technology cooperation: promoting cooperation in implementing Viet Nam’s 10 strategic technology sectors; attracting Korean enterprises to invest in high-tech areas; promoting connectivity in green and digital infrastructure, strategic supply chains, and supporting industries; developing regional industry clusters; expanding cooperation on standards and mutual recognition; and participating in supply chains...

On behalf of the National Assembly of the RoK, I warmly welcome Vietnamese National Assembly President Tran Thanh Man’s visit to the RoK. Since the administration of President Lee Jae Myung took office in June 2025, the two countries have held three high-level exchanges within just six months. This is evidence of the close cooperative relationship between the RoK and Viet Nam.


As the two countries will celebrate the 35th anniversary of the establishment of diplomatic relations next year, I believe this will be a turning point for the two sides to establish new milestones in the development of their friendship and cooperation.

National Assembly President Tran Thanh Man’s visit at this important juncture will contribute to further promoting exchanges between the two legislative bodies while providing important momentum for elevating bilateral cooperation. Parliaments are an important pillar of national governance and also play an essential role in facilitating and supporting bilateral cooperation.

I believe relations between the two countries can continue to develop through active exchanges and cooperation between the two governments, including mutual visits by the two countries’ leaders, as well as the full and effective implementation of bilateral agreements.

Through this visit, I look forward to having an extensive exchange with Vietnamese National Assembly President Tran Thanh Man on how the two countries’ parliaments can facilitate and provide the necessary legislative support for this process.

The visit is important both bilaterally and in terms of parliamentary cooperation, reaffirming the consistent importance that the Party, State, and National Assembly of Viet Nam attach to the Comprehensive Strategic Partnership between Viet Nam and the RoK. The visit aims to transform Viet Nam–RoK relations from a sound political framework into concrete, measurable results that bring practical benefits to the people and businesses of both countries.

Parliamentary cooperation stands as a cornerstone of the Comprehensive Strategic Partnership. I hope the trip will catalyse fresh advancements across three distinct vectors. First, it will sustain regular exchanges between leaders of the two legislatures, specialised committees, and lawmakers, thereby enhancing mutual understanding, sharing expertise, and building consensus on major issues in bilateral relations. Second, it is expected to amplify the supervisory role of the two legislatures in implementing high-level agreements, particularly large-scale programmes and projects with direct impacts on businesses, workers, and people. Third, it will fortify coordination at the Inter-Parliamentary Union (IPU) and regional parliamentary forums, contributing to peace and stability, respect for international law, and the promotion of ASEAN centrality.

The Viet Nam–RoK and RoK–Viet Nam parliamentary friendship groups should continue to serve as flexible, practical conduits. Lawmakers should not only foster friendship but also help proactively identify and resolve challenges concerning businesses, workers, the Vietnamese community, and multicultural families. Parliamentary cooperation therefore plays both a pioneering role and a part in underwriting the continuity and resilience of bilateral relations.

Advancing the Viet Nam–Mongolia comprehensive partnership

Under the leadership and stewardship of the ruling Mongolian People's Party (MPP), Mongolia's economy has maintained steady expansion, driven by key sectors including mining, exports, livestock farming, and foreign investment. The Mongolian Government is vigorously implementing its 2024–2028 Action Programme, the 2026–2030 Development Plan, and the “Vision 2050.” Mongolia pursues a peaceful, independent, self-reliant, multi-pillar, and non-aligned foreign policy, while deepening broad and substantive cooperation with its “third neighbours,” including Viet Nam.

The traditional friendship between Viet Nam and Mongolia was established and meticulously cultivated by President Ho Chi Minh and generations of leaders of the two countries. Viet Nam has always treasured the sentiments and valuable support extended by the Mongolian State and people to Viet Nam during its past struggle for independence, as well as in its nation-building and development today. Viet Nam supports Mongolia’s major development trajectories, its efforts towards integration, and its endeavours to enhance its role and standing in the international arena. Mongolian leaders have affirmed that Viet Nam is regarded as one of Mongolia’s leading partners in Southeast Asia.

The Viet Nam–Mongolia Comprehensive Partnership has developed positively, yielding a multitude of substantive and highly encouraging outcomes. Party-to-Party relations have been strengthened; political trust has been consolidated; and exchanges of delegations and high-level contacts, as well as exchanges at various levels and between localities, have been sustained. Defence, security, judicial, and law-enforcement cooperation is emerging as a crucial pillar of bilateral relations, with a number of new and substantive developments. Economic, trade, and investment cooperation has continued to flourish through agreements, commitments, and cooperation projects, while the Viet Nam–Mongolia Intergovernmental Committee on Economic, Trade, Scientific, and Technical Cooperation has convened regularly. Cooperation in other areas, including culture, tourism, education, agriculture, local-level cooperation, and people-to-people exchanges, has also continued to broaden.
Cooperation between the two National Assemblies has been sustained, with delegation exchanges and contacts through parliamentary channels further accelerated. The two sides agreed to fortify cooperation between their legislative bodies, particularly among specialised committees, parliamentary friendship groups, young and female parliamentarians, and affiliated agencies, in alignment with the new framework of bilateral relations. They also agreed to continue coordinating and supporting each other at regional and international inter-parliamentary forums, including the Inter-Parliamentary Union (IPU), the Asia-Pacific Parliamentary Forum (APPF), and the Asia-Europe Parliamentary Partnership (ASEP).

Viet Nam stands ready to work closely with Mongolia to usher parliamentary cooperation between the two countries into a new, more substantive stage of development by deepening cooperation between their legislative bodies and encouraging the two Governments to effectively implement signed agreements. Viet Nam has also proposed that Mongolia create favourable conditions for Vietnamese businesses and citizens to conduct business and live securely in the country over the long term. More substantive cooperation between the two legislatures will contribute to bolstering bilateral cooperation in national defence, security, and the economy, particularly in science and technology and other emerging areas, commensurate with the scope of the Viet Nam–Mongolia Comprehensive Partnership.

National Assembly Chairman Tran Thanh Man’s official visit to Mongolia is of great significance, taking place at a time when Viet Nam–Mongolia relations are developing very dynamically and have recently been upgraded to a Comprehensive Partnership. The visit serves as a pivotal catalyst for the two sides to translate major commitments and orientations agreed upon by their senior leaders into concrete action, demonstrating their resolve to deepen the Comprehensive Partnership and make it more substantive and effective.

The official visits to the RoK and Mongolia by National Assembly President Tran Thanh Man and his spouse, accompanied by a high-ranking Vietnamese delegation, vividly illustrate Viet Nam’s foreign policy of independence, self-reliance, peace, friendship, cooperation, and development, as well as the diversification and multilateralisation of its external relations.
Robust coordination between the Vietnamese National Assembly and the legislatures of the RoK and Mongolia at prestigious global and regional parliamentary forums will help amplify the voice for peace and respect for international law. The visits will also contribute to further advancing exchanges between the legislative bodies, creating crucial momentum for a new stage of cooperation between Viet Nam, the RoK, and Mongolia, for peace, cooperation, and development in the region and the world.
