公约

• Pinyin: gōng yuē
• Hanzi breakdown: 公 = collective, public; 约 = 纟 (thread/binding) + 勺 — to bind, agreement

Meaning

Convention; pact; collective agreement. A binding agreement voluntarily entered into by multiple parties, organisations, or states.

Used in both international diplomacy and community contexts. 国际公约 (international convention) governs the conduct of states; 居民公约 (residents' charter) regulates community behaviour. Differs from 条约 (treaty), which is strictly inter-state. Implies mutual, voluntary commitment among multiple participants.

2. 全班同学共同制定了一份诚信自律公约，并签名承诺遵守。 The whole class drew up an integrity and self-discipline pact together and signed their names, pledging to follow it.
