公约 (gōng yuē): convention (i.e. international agreement)

To protect the marine environment, representatives of various countries signed an international convention at the United Nations, promising to reduce plastic waste.

This convention stipulates that all signatory states must regularly report on their human rights situation.

Although some countries have not yet ratified the convention, it has become an important reference in international law.

At the climate change conference, after intense negotiations, countries finally adopted a new emission reduction convention.

Scholars pointed out that the provisions of this convention need to be continuously updated in light of technological development.
