10 Yuan Hainan Tropical Rainforest National Park

Hainan's tropical rainforest was designated China's first national park under the new national park system formalized in October 2021, a policy shift that ended decades of fragmented provincial reserve management on the island. This coin follows the People's Bank's well-established commemorative circulation bimetallic program, which has documented threatened ecosystems and protected zones since the 1990s — the Hainan gibbon, the world's rarest ape with a wild population still under forty individuals, is among the species the park was explicitly created to protect.
