What this dot point is asking
VCAA wants you to study the United States in depth as the established power working to maintain its position in the Asia-Pacific. You need to explain its national interests, the instruments of power it uses, and how effectively it sustains its role as a rising China challenges it. This is a single-actor study paired with China's rise. Exam questions ask you to analyse the United States' national interests or evaluate its regional power, so you need specific instruments and current examples.
The answer
United States national interests
The United States pursues a clear set of interests in the region.
- Maintaining the regional order. It seeks to preserve the rules-based order it built and to prevent any single power, namely China, from dominating the region.
- Security and alliances. It seeks to protect its allies and partners, secure freedom of navigation and uphold its forward military presence.
- Economic prosperity. It seeks access to the region's markets, secure supply chains, and leadership in the technologies that will shape the future economy.
Instruments of power
The United States is distinctive for the depth of its military and alliance instruments.
- Military power. It maintains the most capable armed forces in the region, with bases, fleets and forward deployments that underpin deterrence and freedom of navigation operations in contested waters.
- Alliances and partnerships. Its network of treaty alliances, including with Japan, South Korea, the Philippines and Australia, and newer groupings such as the Quad and AUKUS, multiplies its reach and binds partners into a balancing coalition.
- Economic and diplomatic power. It uses trade, investment, technology controls and diplomacy, framed around a free and open Indo-Pacific, to sustain influence, though its economic engagement has at times lagged its security role.
- Soft power. American culture, universities, technology and values continue to draw the region toward it, reinforcing its position.
Evaluating its ability to maintain its position
The United States remains the strongest single military actor in the region, but its dominance is no longer unchallenged.
- Strengths. Its alliance network is unmatched, its military remains the most capable, and its soft power endures. The balancing coalition it leads constrains China's freedom of action.
- Limits. China's economic centrality means many states depend on it even as they rely on the United States for security, creating a hedging dynamic. Doubts about the consistency of United States commitment, and its lighter economic engagement, weaken its hand. The regional balance has shifted toward a contest rather than clear United States primacy.
A defensible judgement is that the United States retains the instruments to sustain a leading role and to balance China, but it can no longer assume uncontested dominance and increasingly relies on partners to share the burden.
Examples in context
Example 1. Balancing through new groupings. AUKUS commits Australia, the United Kingdom and the United States to share nuclear-powered submarine technology, while the Quad coordinates the United States, Japan, India and Australia. These show the United States using alliances and partnerships to multiply its reach and balance a rising China rather than relying on its own forces alone.
Example 2. The hedging dilemma for partners. Regional states such as Australia depend on the United States for security yet on China as their largest trading partner. This forces them to hedge, supporting the United States-led order while protecting economic ties with China, which both sustains and complicates the United States position.

Exam-style practice questions
Practice questions written in the style of VCAA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
2020 VCAA3 marksUsing one specific example, explain one factor that shapes this Asia-Pacific state's attempts to achieve national security. [one Asia-Pacific state must be used: Australia, China, Indonesia, Japan or the United States of America]Show worked answer →
Three marks: identify one factor, explain how it shapes the pursuit of national security, and give a specific example. With the United States selected, this tests US national interests directly.
A key factor shaping US national security is the rise of China as a strategic rival. This factor drives the US to reinforce alliances and forward presence to deter Chinese expansion and preserve the regional balance.
Specific example: the US Indo-Pacific strategy, including AUKUS and the strengthening of the Quad (US, Japan, India, Australia), is a direct response to China's growing power. Markers want one clearly named factor, a causal link to how it shapes the security effort, and a real example.
2022 VCAA4 marksExplain how trade has been used by this Asia-Pacific state in an attempt to achieve the national interest of national security. [Australia, China, Indonesia, Japan or the United States of America]Show worked answer →
Four marks: explain the link between the instrument of trade and the national security interest for your chosen state, with a contemporary example. This tests the United States' instruments of power.
For the United States, trade is used as a security instrument in two ways. First, economic statecraft against rivals: tariffs on Chinese goods and export controls on advanced semiconductors and technology are designed to slow a strategic competitor's military-relevant capabilities, directly serving national security.
Second, trade ties that bind partners: preferential access and supply-chain cooperation with allies such as Japan strengthen the alliances on which US regional security rests.
Markers want a clear explanation of how trade (not just generic economic power) advances national security, supported by a real, recent example. The strongest answers note trade can also create vulnerabilities (dependence, retaliation), showing the instrument has limits.
