Involving two parties, especially two sovereign countries.

Specifically describes trade pacts or diplomatic treaties negotiated directly between two nations.

The story behind the word. Bilateral combines Latin 'bi-' (two) and 'lateralis' (from 'latus', meaning side). Thus it literally means 'two-sided', entering legal and diplomatic usage in the 18th century to describe binding two-party contracts.
