Multilingual Communication in Diplomacy

Language as a Power Dynamic

The United Nations has six official languages: Arabic, Chinese, English, French, Russian, and Spanish. In practice, English dominates — roughly 85 percent of UN Secretariat communications are in English, and most informal negotiations at the UN happen in English. This creates an inherent advantage for native English speakers and a structural disadvantage for everyone else.

This is not just about convenience. Research shows that people negotiate more aggressively, use more nuanced arguments, and deploy more sophisticated persuasion techniques in their native language. A brilliant diplomat from Japan or Senegal may be operating at 70 percent capacity when negotiating in English — not because of intelligence, but because of the cognitive overhead of working in a second language.

Understanding this dynamic matters for MUN delegates for two reasons. First, if English is your first language, recognize the advantage you have and be aware that other delegates may be working harder to communicate the same ideas. Second, if English is not your first language, know that your challenge is real but manageable — and that the preparation techniques in this lesson can level the playing field.

The Role of Interpretation

At the real UN, simultaneous interpreters translate speeches in real time into all six official languages. This is an extraordinary feat — and it introduces layers of meaning-making that speakers must account for.

What changes when your speech will be interpreted:

• Speak at a measured pace. Interpreters need time to process and translate. Rapid speech forces them to summarize rather than translate, which means your nuances are lost.
• Use clear sentence structures. Simple, declarative sentences translate better than complex, nested clauses. 'This proposal will increase costs' translates cleanly. 'While not entirely without merit in certain specific contexts, the proposal as currently drafted raises concerns that, if left unaddressed, could potentially result in increased costs' does not.
• Avoid idioms and cultural references. 'The ball is in their court' has no equivalent in most languages. 'We are waiting for their response' communicates the same idea universally.
• Key terms should be precise. In diplomatic negotiation, the difference between 'requests,' 'urges,' 'demands,' and 'calls upon' is legally significant. Use these terms deliberately because interpreters will translate them precisely.

While most MUN conferences operate in English without interpretation, understanding these dynamics makes you a more thoughtful communicator — and prepares you for professional diplomatic environments.

Strategies for Non-Native English Speakers

If English is your second or third language, specific preparation strategies can close the gap:

• Script your key phrases in advance. You do not need to script every word, but having your most important sentences pre-written ensures they come out exactly as intended. Diplomatic precision matters more than spontaneity.
• Build a diplomatic vocabulary list. Master 50 key diplomatic phrases in English and practice them until they are automatic: 'We express grave concern,' 'My delegation is not in a position to support,' 'Without prejudice to our position.' When these phrases flow naturally, you sound diplomatic regardless of accent.
• Slow down deliberately. Speaking slowly in a second language sounds authoritative. Speaking quickly sounds uncertain. A measured pace also gives you time to select the right words.
• Use your accent as identity. Your accent is your delegation's national voice. A Brazilian delegate who speaks English with a Portuguese accent is representing Brazil — the accent reinforces rather than undermines your role. Never apologize for it.
