The economic component of Vietnam and Australia's upgraded partnership will help Vietnam achieve its green energy ambitions and grant Australia greater access to one of Southeast Asia's fastest-growing markets, while the defense component portends increased bilateral cooperation on efforts aimed at improving maritime security in the region. Australia and Vietnam upgraded their bilateral relationship to a comprehensive strategic partnership, Vietnam's top-tier diplomatic designation, on March 7. The upgrade occurred after Australian Prime Minister Anthony Albanese and Vietnamese Prime Minister Pham Minh Chinh met bilaterally following an Australia-Association of Southeast Asian Nations (ASEAN) summit, which ran from March 4-6. This development also follows a memorandum of understanding on energy and mineral cooperation that Australia and Vietnam signed at the same venue on March 6.

• Australia and Vietnam have discussed potentially upgrading their ties since late 2022. Momentum picked up in April 2023 when Australian Governor-General David Hurley visited Hanoi and agreed in principle to the upgrade with Vietnamese State President Vo Van Thuong.
• Australia and Vietnam normalized relations in 1973 after Australia pulled out of the Vietnam War. The two countries established a third-tier comprehensive partnership in 2009 (enhanced in 2015), and then a second-tier strategic partnership in 2018.

The upgrade in ties aligns with both countries' desire to diversify their security and economic partnerships in the region in light of China's growing assertiveness and U.S. policy uncertainty. For Vietnam, the decision is in line with the 13th National Party Congress' foreign policy directive to deepen ties with regional countries. It also tracks with other recent developments — namely, Vietnam's moves to similarly upgrade ties with South Korea in December 2022, the United States in September 2023, and Japan in November 2023 to top-tier comprehensive strategic partnerships. Vietnam has recently sought to deepen its relations with the Western world and its Asian allies in the hopes of securing the financing, technical know-how and market access Vietnam needs to achieve its goal of becoming a high-income economy by 2024. Hanoi's push to diversify its foreign partnerships is also largely aimed at hedging against China in the two countries' territorial dispute in the South China Sea. Australia, for its part, shares considerable geopolitical interests with Vietnam and other emerging middle powers in Southeast Asia, including a desire for maritime security, renewable energy development and supply chain resiliency, as well as a need to navigate the escalating U.S.-China rivalry. As such, Southeast Asia's robust development benefits Australia from a security perspective by providing a counterweight to China's influence, as well as from an economic perspective by providing a sizable market for Australian exports, particularly green energy products (like solar panels and wind turbines). For Australia, China's moves to impose punitive restrictions on various Australian imports in recent years have only increased Southeast Asia's strategic importance by prompting Canberra to look for more reliable trade markets — or ones where the risk of economic coercion is lower. Moreover, for regional countries, the prospect of a second Donald Trump administration in the United States necessitates bilateral arrangements in the event that the United States again moves to disengage from Southeast Asia, as it did during Trump's first term.

• Vietnam upgraded its relationships with China (2008) and Russia (2012) to comprehensive strategic partnerships long before it did so with Australia, South Korea, the United States and Japan. This showcases Vietnam's so-called ''bamboo diplomacy'' or multi-alignment (as opposed to non-alignment) as the world becomes increasingly multipolar, which has seen Hanoi maintain a deep economic relationship with China, as well as close political, defense and energy ties with Russia (Vietnam's traditional and long-time patron dating back to the Cold War era) — even as it pursues deeper ties with Western powers and other Asian neighbors. Indeed, in 2024, Vietnam could similarly upgrade ties to its top level with Singapore, the Philippines, Indonesia and Thailand, highlighting the many vectors of tightening regional cooperation on bilateral and multilateral bases in the context of shifting geopolitics.
• In 2020, China imposed restrictions on various Australian imports after the Australian government called for an investigation into the origins of COVID-19. Over the past six months, China has lifted many of these restrictions, including those on coal, beef and barley products. But it has yet to lift its import ban on Australian wine, despite promising to do so during Prime Minister Albanese's visit to Beijing in November 2023.

The upgrade in ties will primarily focus on economics, which will provide Australian companies more trade and investment opportunities, while helping Vietnam meet its current and future energy needs. According to Vietnamese Prime Minister Chinh, the agreement will focus on five key areas: political trust; trade and investment; science, technology and innovation; education, training, culture and people-to-people exchanges; and tourism and labor. This highlights that the upgrade will be primarily economic in nature. Australia currently provides Vietnam with 44% of its coal supplies, which the Southeast Asian country still heavily relies on to power its electric grid. For Hanoi, Australia's status as the world's second-largest exporter of liquified natural gas (LNG) makes it an all the more attractive trade partner, as LNG is a key resource for economic development and the energy transition that Vietnam anticipates it will need to import to the tune of 4 billion cubic meters per year through 2025 (according to the country's gas industry development plan), and even more thereafter. As part of their upgraded partnership, Vietnam and Australia will establish a ministerial-level dialogue on energy, likely leading to increased coal and LNG trade at prices more favorable to Vietnam. On green energy, Vietnam intends to be carbon-free by 2050, meaning the massive capital investment required for this alone would afford Australian companies engaged in green energy substantial business opportunities in Vietnam. For Vietnam, such Australian investment would provide it with the technical know-how and green infrastructure it needs to boost its wind and solar power capacity — particularly as the Mekong Delta, which Vietnam has long relied on to generate hydropower, rapidly dries up due to climate change. 

• Australia, along with Japan, is the top contributor to Vietnam in terms of official development assistance, providing over $650 million in grants since 2000 and around $40 million per year in the last five years. Bilateral trade topped $13.8 billion in 2023, rendering each country a top-ten trade partner of the other.
• As part of their upgraded ties, Australia and Vietnam will also build off of existing multilateral trade partnerships, such as the ASEAN-Australia-New Zealand Free Trade Agreement, the Regional Comprehensive Economic Partnership and the Comprehensive and Progressive Agreement for Trans-Pacific Partnership.
• Education links between Australia and Vietnam (which are already strong) are set to strengthen as well, with more Vietnamese students studying in Australia. There are currently over 100 agreements between Australian and Vietnamese universities, including 20 that provide Australian qualifications to Vietnamese students) — a number that will likely grow in light of the two countries' newly upgraded partnership. This will complement a recent announcement by Australia's RMIT University Vietnam that the school plans to invest $250 million in its in-country operations in 2023.
• The upgraded partnership could incorporate the Australia-Vietnam Partnership for Economic Growth, a program proposed in July 2023 that would see Australia contribute $50 million between 2024 and 2029 to Vietnam's energy transition, with the deal extendable every five years.

The move to upgrade ties will also see Vietnam and Australia enhance their modest defense partnership. While Chinh did not explicitly mention defense and security, upgrading ties to a comprehensive strategic partnership also implies an upgrade in defense ties. This is reflected in Australia and Vietnam's joint statement, though neither country is interested in highlighting this component over economic considerations given its sensitivities, particularly vis-a-vis China. Nonetheless, Vietnam and Australia will enhance their limited defense partnership, building on an annual defense dialogue at the deputy-ministerial level. This collaboration will focus on areas such as intelligence sharing, cybersecurity, police and coast guard cooperation, as well as efforts against illegal, unreported, and unregulated fishing (for which China is the largest perpetrator regionally). It will also likely lead to port calls made to Vietnam by the Australian navy. In addition, Australia and Vietnam's joint statement affirmed each country's commitment to the United Nations Convention on the Law of the Sea (UNCLOS). This is a veiled shot at China's activities in the South China Sea amid its dispute with Vietnam (and other countries), and signals Australian support for Vietnam in that dispute, because China typically disregards UNCLOS, of which it is a signatory. Closer ties with Vietnam will also enable Australia to stretch its maritime strategic space amid competition with China for influence in the Pacific Islands and, increasingly, Southeast Asia. Such deeper defense cooperation between Vietnam and Australia, however, will still fall well short of a military alliance.

• ASEAN countries are broadly opposed to security blocs in their region, as demonstrated by Indonesia's and Malaysia's negative reactions to the 2021 signing of the AUKUS security pact between Australia, the United States and the United Kingdom, which took most of the Southeast Asian bloc by surprise.
