In northeastern China, the populations of wild tigers and leopards have experienced significant growth. Over the past year, more than 35 cubs have been born, including over 20 Siberian tiger cubs and more than 15 Amur leopard cubs. These animals now inhabit an area exceeding 1.1 million hectares, which constitutes approximately 78% of the Northeast China Tiger and Leopard National Park's total area.

Siberian tigers, also known as Amur tigers, primarily reside in Russia's Far East and Northeast China. With an estimated population of around 500 individuals in the wild, they are considered one of the world's most endangered species. Similarly, Amur leopards, also known as Far Eastern leopards, are among the most critically endangered felines globally.

In October 2021, China established the Northeast China Tiger and Leopard National Park, encompassing over 1.4 million hectares in the northeastern provinces of Jilin and Heilongjiang. The park has implemented various conservation measures, including the removal of factories and mines, as well as the restoration of forest vegetation, to safeguard the well-being of these endangered species.
