China now has 15 World Natural Heritage sites, leading in the total number of World Natural Heritage sites worldwide. It also has four mixed cultural and natural heritage sites.

The Badain Jaran Desert, located in the Inner Mongolia autonomous region, is China's third-largest desert.

Scattered among the towering dunes are numerous lakes, showcasing a typical and ongoing process of aeolian landform development on Earth, while also serving as a rich and diverse habitat for wildlife, the administration said.

Within the Badain Jaran Desert are the world's tallest fixed dunes, the most densely distributed desert lakes and a variety of wind-sculpted landforms.

The other nomination, the migratory bird sanctuaries, is a serial extension of the property of the same name that is already listed on the World Heritage List. The newly admitted five sites, namely an estuarine wetland in Chongming, Shanghai; the Yellow River estuary in Dongying, Shandong province; a wetland area in Cangzhou, Hebei province; a national-level nature reserve in Dalian, Liaoning province as well as the Yalu River estuary in Dandong, Liaoning, are part of Phase II, while Phase I sanctuaries, were inscribed on the World Heritage List in 2019.

According to the administration, the sanctuaries provide breeding, resting and wintering grounds for tens of millions of waterbirds.
