Translation guide
The English word 'multilateral' is most commonly used in formal, political, or diplomatic contexts to describe agreements, talks, or relationships involving multiple parties. In Japanese, the concept is expressed through specific Sino-Japanese compounds, primarily 多国間 (takokukan) for 'among multiple countries' and 多角的 (takakuteki) for 'from multiple angles or perspectives'. The choice depends on whether the focus is on the number of parties or the multifaceted nature of the approach.
Describing agreements, negotiations, or relations that involve three or more nations or groups.
The standard term for 'multilateral' in international relations. Used as a pre-noun modifier (e.g., 多国間の～).

多角的な協定
multilateral agreement
多国間 (takokukan) specifically means 'among multiple countries' and is used for international relations. 多角的 (takakuteki) means 'multifaceted' or 'from many angles' and is broader. In diplomatic contexts, both can translate 'multilateral', but 多国間 is more precise for country-to-country matters.
Do not try to translate 'multilateral' as 多側面 (tasokumen) or 多辺 (tahen). These are not standard and will sound unnatural. Stick to the compounds listed above.
