National interests include a country's security, independence and long-term prosperity. Government uses cooperation, diplomacy and defence to pursue them.
Protecting national interests concerns the country's ability to remain secure, make its own decisions and sustain its people. For Singapore, relations with other countries matter because trade, supply routes and regional stability affect daily life. National interests are wider than the advantage of one company or political party.
Diplomacy uses relationships, discussion and negotiation to manage differences and cooperate. Bilateral cooperation involves two countries; multilateral cooperation involves several, such as through the Association of Southeast Asian Nations, or ASEAN. Agreements can support trade, shared problem-solving and peaceful relations, but require follow-through.
Deterrence aims to discourage aggression by making an attack less likely to succeed or more costly. Defence capability and preparedness can contribute to it. Diplomacy and deterrence can work together: communication can reduce misunderstandings, while trained and equipped forces make an attack harder to carry out. Neither guarantees that every disagreement or threat disappears.
Worked example: Keeping essential supplies moving
A small country depends on imported medicines. Its government negotiates supply arrangements with several partners and works with neighbouring countries to keep shipping routes safe.
- The national interest is reliable access to essential supplies, linked to people's health and the country's ability to cope with disruption.
- Negotiation and cooperation address a problem that cannot be solved entirely within one country's borders. Several partners can reduce dependence on a single relationship.
- An agreement shows a commitment. Successful deliveries show more, but we still need to know whether enough supplies reach those who need them and whether they would have arrived without the agreement.
Watch out for this
Protecting national interests means avoiding cooperation and relying only on military strength.
Cooperation can serve national interests by improving security, access and stability. Explain how diplomacy and deterrence address different parts of a challenge.
Check your understanding
Two countries agree to share warnings about hazards along an important shipping route. How could this serve a national interest?
- Signing the agreement proves that trade can never be disrupted.
- Timely warnings can help protect ships and the supplies they carry, if both countries act on the agreement.
- It benefits national interests only if one country gains and the other loses.
