Antarctic Treaty (1959)
Twelve countries signed a treaty reserving Antarctica for peaceful purposes, freezing territorial claims, and promoting scientific cooperation. It became the legal foundation for all later Antarctic governance.
Militarization and new sovereignty claims were halted.
The treaty created a consultative-party system that now includes 29 decision-making states, China among them since 1985.
China's new law is explicitly framed as domestic implementation of the treaty it joined in 1985.
