Foreign Policy Balancing Act as Small States Navigate Growing Great-Power Rivalries

Great-power rivalry is becoming the defining condition of foreign policy. It is not only about military posture. It now shapes trade, technology, finance, and even standards for data and supply chains.

For small states, the pressure is sharper. They depend on open routes. They rely on stable rules. And they often sit near flashpoints they cannot control. Still, they are not passive players. They adapt, bargain, and build room to manoeuvre.

In Southeast Asia, that balancing act is visible every day. It is also becoming harder as competition intensifies between United States and China.

Why balancing is harder now

Small states used to manage rivalry with quiet diplomacy and flexible trade ties. Today, the contest is more embedded in policy.

Export controls limit who can buy advanced technology. Investment screening changes where capital can flow. Sanctions and secondary risks can reach firms far from the original dispute. As a result, a commercial decision can become a geopolitical signal.

This also raises the cost of mistakes. A misstep can trigger reputational damage, lost market access, or tighter scrutiny from partners.

How small states diplomacy works in practice

Balancing is not neutrality in the old sense. It is active positioning.

Small states typically try to avoid exclusive alignment. They keep channels open with all major powers. They also build “option value” by widening partnerships, so no single relationship becomes existential.

Option value is the benefit of keeping choices available when the future is uncertain. In diplomacy, it can mean more trade corridors, more security dialogues, and more investment sources.

Singapore’s playbook is about agency

Singapore sits at the centre of global flows. It is an air and sea hub. It is also a finance and data gateway. That brings prosperity, but it also creates exposure.

Prime Minister Lawrence Wong has argued that small states still have agency, even when the world becomes more fractured. The core idea is straightforward. A small state cannot shape the rivalry alone. However, it can shape its own resilience and credibility.

That translates into three priorities. First, stay open to trade and investment. Second, uphold rules consistently. Third, invest in long-term competitiveness so external shocks hurt less.

Regional cooperation is the shield, not a slogan

For many small states, the strongest leverage comes from acting with others.

ASEAN is central to this strategy. It offers convening power. It also provides a platform for joint positions, even when members differ on specifics.

That unity is under strain. Yet leaders keep returning to the same principles: dialogue, restraint, and respect for international law. Those principles matter because they slow escalation and make space for compromise.

The message has also been repeated by regional chairs. The Philippines has emphasised rules and diplomacy as it shapes the bloc’s agenda, including efforts to manage tensions in the South China Sea.

Neutrality is under pressure across Southeast Asia

Balancing does not mean avoiding hard choices forever. Rivalry forces decisions, often in small steps.

Some choices involve defence cooperation. Others involve supply chain policy. Many involve technology, where partners ask for alignment on standards and controls.

Regional leaders have acknowledged this squeeze openly. Malaysia has warned that ASEAN’s space to stay neutral is being eroded as competition intensifies.

That concern reflects a wider shift. Great powers increasingly see ambiguity as a risk. They want clarity. Small states often prefer flexibility.

Rules-based order is not abstract for small states

Small states put a premium on rules because power gaps are real.

International law does not eliminate coercion. However, it creates standards that can rally partners. It also provides language for protest and coalition-building.

This is why many small states anchor their diplomacy in the United Nations system. They push for consistent application of principles, especially sovereignty and peaceful settlement of disputes.

In practice, this approach works best when it is backed by credibility. That means applying rules even when it is inconvenient.

Hedging is no longer only about security

In the past, “hedging” often referred to defence. Today, it is economic too.

Countries diversify trade routes. Firms split production across sites. Governments build redundancy in energy and food supply. They also invest in cyber resilience and critical infrastructure.

Hedging means taking steps that reduce risk without making a single, irreversible bet. It is costly. However, it can prevent bigger losses when shocks hit.

Economic statecraft forces tougher trade-offs

Small states are now navigating a world where economics is a tool of pressure.

Tariffs can be political. Investment can come with strategic expectations. Tech access can be conditioned on alignment. This makes it harder to keep foreign policy separate from industrial strategy.

For businesses, it also increases compliance risk. A contract can be legal in one market and restricted in another. A supplier can become sensitive overnight because of new controls.

That is why many governments are urging companies to map supply chains more deeply. They want better visibility on end users, ownership, and data flows.

Crisis management is becoming a constant skill

Rivalry increases the frequency of crises. Not all crises become conflicts. Yet each one can disrupt markets and confidence.

Small states respond by strengthening channels for de-escalation. They keep defence hotlines. They maintain diplomatic access even when tensions rise. They also support multilateral forums that bring rivals into the same room.

At the same time, they prepare at home. That includes public communications, contingency planning, and stronger coordination between economic and security agencies.

What the next phase will demand

The balancing act will not get easier. Rivalry is expanding into new domains, including AI, critical minerals, and undersea cables. It is also spreading beyond two powers, as more countries pursue strategic autonomy.

For small states, success will depend on discipline and consistency. They will need to keep partnerships broad, not exclusive. They will need to invest in resilience, not only efficiency. And they will need to defend rules not with slogans, but with steady, credible behaviour.

Small states cannot stop great-power competition. However, they can shape how much it harms them. In Southeast Asia, that is the real test of diplomacy in the years ahead.
