Key Security Developments

• Diplomatic Engagements with the United States
  Vietnamese President To Lam led a high-level delegation to the United States from September 20 to 23, attending the 81st session of the UN General Assembly and engaging in bilateral activities. During his visit, President Lam indicated that Vietnam is "very close" to a trade deal with the US, expressing a desire to increase imports of high-tech US goods such as aircraft, nuclear power, and road and railway infrastructure to narrow the trade gap. This visit underscores Vietnam's efforts to balance relations with major strategic partners amidst global tensions.

• Deepening US-Vietnam Defense and Maritime Security Cooperation
  On September 22, President To Lam met with Acting Secretary of the US Navy Hung Cao in New York to discuss enhancing Vietnam-US defense cooperation. Discussions focused on maritime security, capacity building, humanitarian assistance, and disaster response within the framework of their Comprehensive Strategic Partnership. Furthermore, on September 23, Vietnam and the US signed a Limited Scope Project Agreement (LSPA) at the Ministry of National Defense headquarters to implement projects addressing post-war toxic chemical/dioxin consequences in Vietnam, with Vietnam committing VND 353 billion in counterpart funding.

• New Strategic Partnership with Canada
  Following his engagements in the US, President To Lam paid a state visit to Canada from September 20 to 25, where Canada and Vietnam launched a new Strategic Partnership on September 26. This partnership aims to deepen cooperation across political, security, and economic issues, building on over 50 years of diplomatic ties and linking to wider Indo-Pacific engagement, including progress toward an ASEAN-Canada Free Trade Agreement.

• Strengthening EU-Vietnam Comprehensive Strategic Partnership
  The seventh meeting of the EU-Vietnam Joint Committee was co-chaired by Deputy Minister of Foreign Affairs Le Thi Thu Hang and Managing Director for Asia and the Pacific at the European External Action Service Erik Kurzweil in Hanoi on September 25-26. The meeting affirmed the positive and substantive development of relations, particularly since their elevation to a Comprehensive Strategic Partnership in January 2026. Both sides agreed to enhance cooperation in trade, investment, sustainable development, and defense and security, while also stressing the importance of resolving East Sea (South China Sea) disputes peacefully in accordance with UNCLOS 1982.

• Preparations for Vietnam Defense Expo 2026
  As of September 21, 2026, 134 organizations and companies from 32 countries, including the US, China, and Russia, had registered to participate in the Vietnam Defense Expo 2026, scheduled for December 10-13 at Gia Lam Airport in Hanoi. A conference of the Steering Committee on September 24 revealed that Vietnam's defense industry plans to introduce 579 products and services, including 48 new categories compared to the 2024 edition. US partners are expected to showcase outdoor products such as the C-130J transport aircraft, M142 High Mobility Artillery Rocket System (HIMARS), M777 155mm howitzer, and Stryker M1126 armored vehicles.

• Cybersecurity Policy and Digital ID Expansion
  The Ministry of Public Security (MPS) proposed a draft law on September 24 granting police the authority to disconnect internet and telecommunications services for individuals failing to pay administrative fines. This follows the implementation of new decrees (332, 333, 341) in August and September 2026, which detail provisions of the 2025 Cybersecurity Law, introducing new licensing requirements for cybersecurity businesses, data localization rules, and stronger obligations for online platforms.

• Counter-Transnational Online Scams Initiative
  At the 2026 International Conference on Combating Online Scams (ICCOS-2026) in Phnom Penh on September 23, Deputy Minister of Public Security Sen. Lieut. Gen. Nguyen Van Long proposed that each country establish specialized coordination task forces to verify, investigate, and handle complex transnational scam rings. He emphasized that online scams are a global issue affecting national security and called for enhanced information exchange and coordinated investigations.

• Enhanced International Standing in Maritime Law
  Vietnam secured its first-ever seat as a judge on the International Tribunal for the Law of the Sea (ITLOS) for the 2026-2035 term. This achievement reflects Vietnam's growing recognition and active role in shaping and upholding international maritime law, further solidifying its commitment to the 1982 United Nations Convention on the Law of the Sea (UNCLOS).

• Ongoing Russia-Vietnam Defense and Energy Ties (Contextual)
  While occurring just outside the reporting period (September 9), President To Lam's meeting with Russian President Vladimir Putin in Moscow highlighted Russia's historic role as Vietnam's largest military supplier and discussed deepening economic and defense ties. Energy cooperation, including plans for a Russian-designed nuclear power plant in Vietnam, was also a major focus, providing important context for Vietnam's diversified defense and energy partnerships.

Geopolitical Impact and Regional Dynamics

Vietnam's diplomatic activities during this period underscore its strategic balancing act amidst intensifying global and regional competition. President To Lam's high-profile visits to the US and Canada, coupled with ongoing engagement with the EU, demonstrate a clear strategy of diversifying partnerships to enhance national security and economic resilience. The pursuit of a trade deal and increased high-tech imports from the US, alongside defense cooperation in maritime security, signals Vietnam's intent to strengthen ties with Western powers, potentially as a counterweight to regional pressures. This approach is crucial for Vietnam, particularly in the South China Sea, where its priority is deterrence rather than power projection against China's assertive maritime incursions.

Simultaneously, Vietnam's continued engagement with Russia, its traditional military supplier, for defense and energy cooperation, including a nuclear power plant, illustrates its commitment to maintaining a multi-directional foreign policy. This "bamboo diplomacy" allows Vietnam to leverage relationships with various major powers without becoming overly reliant on any single one. The elevation of the EU-Vietnam relationship to a Comprehensive Strategic Partnership and the discussions on upholding international law, particularly UNCLOS 1982 regarding the East Sea, further solidify Vietnam's position as a proponent of a rules-based international order. Vietnam's active participation in multilateral forums, including its new seat on ITLOS and its role in UNGA 81, enhances its international prestige and capacity to shape global norms, contributing to regional stability by advocating for peaceful dispute resolution and multilateral cooperation.

Military and Defense Analysis

Vietnam's military and defense posture during this period reflects a concerted effort towards self-reliance and modernization through diversified international cooperation. The ongoing development of its defense-industrial base is a significant strategic shift, moving from primarily being a buyer of foreign platforms to a domestic producer of sophisticated weaponry. A key milestone in this endeavor was the commencement of construction for Vietnam's largest anti-submarine frigate at Song Thu Corp.'s Da Nang shipyard in August 2026, with full control over engineering at each stage. This domestic naval shipbuilding, combined with land-based anti-ship missiles and emerging submarine capabilities, forms a layered "small shield" designed to enhance deterrence in the contested South China Sea.

The upcoming Vietnam Defense Expo 2026 in December serves as a crucial platform for showcasing these advancements and fostering international defense cooperation. The participation of 134 companies from 32 countries, including major defense players like the US, China, and Russia, highlights Vietnam's open approach to defense acquisitions and technology transfer. The expected display of advanced US military equipment, such as C-130J aircraft, HIMARS, and Stryker armored vehicles, indicates potential future acquisitions or deeper interoperability with Western systems, complementing its traditional reliance on Russian military supplies. This strategy of diversified defense partnerships aims to upgrade military capabilities while maintaining strategic autonomy, allowing Vietnam to acquire the best available technology from various sources to meet its specific defense needs, particularly in maritime security and territorial integrity.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, Vietnam is expected to continue its proactive diplomatic engagements, particularly with the US and Canada, aiming to finalize trade agreements and solidify newly established strategic partnerships. The preparations for the Vietnam Defense Expo 2026 in December will intensify, with further announcements regarding participants and showcased technologies. Domestically, the debate and implementation of new cybersecurity regulations, including the controversial proposal for internet cutoffs for unpaid fines, will likely remain a significant focus, potentially drawing further public and international scrutiny. Vietnam's role in multilateral forums will continue to be prominent, especially concerning maritime law and regional stability, following its recent ITLOS appointment.

Critical flashpoints and risk areas: The South China Sea remains a persistent flashpoint, with China's continued assertive actions posing a significant security challenge for Vietnam. Any escalation or new incidents in these disputed waters could quickly heighten regional tensions. Domestically, the implementation of stringent cybersecurity laws and proposals, such as the internet cutoff for fines, carries the risk of public discontent and concerns over civil liberties, potentially leading to internal stability challenges. Furthermore, Vietnam's delicate balancing act between major powers (US, China, Russia) means that any significant shift in global geopolitical dynamics or increased pressure from one power could force difficult choices for Hanoi.

Indicators to monitor: Key indicators to monitor include the progress and finalization of the US-Vietnam trade deal and any new defense acquisition announcements stemming from the Vietnam Defense Expo 2026. The nature and frequency of maritime incidents in the South China Sea, particularly involving Vietnamese and Chinese vessels, will be critical. Domestically, public and international reactions to the new cybersecurity decrees and the proposed internet cutoff law should be closely watched. Additionally, any high-level diplomatic visits or joint military exercises with key partners will signal the direction of Vietnam's strategic alignments.

Strategic recommendations: Vietnam should continue to prioritize its strategy of diversified defense and economic partnerships to enhance its strategic autonomy and resilience. Investing further in its domestic defense industry, particularly in naval capabilities, will bolster its deterrence posture in the South China Sea. Diplomatically, maintaining open channels with all major powers while consistently advocating for a rules-based international order, especially regarding UNCLOS 1982, is crucial. Internally, while strengthening cybersecurity is vital, the government should ensure that new regulations are implemented transparently and with due consideration for human rights and economic impact to avoid social unrest and maintain investor confidence.
