Chinese scientists claim they have discovered one of the world's largest sinkhole clusters, which contains 19 giant caverns.

The group of caves is situated in the lush forest of Guangxi, a province in southern part of the country bordering Vietnam.

Each single cavern in the group boasts a volume of over one million cubic metres, according to China's Ministry of Natural Resources.

The discovery marks the largest sinkhole cluster to have ever been found south of the Tropic of Cancer, Zhang Haiyuan, a senior engineer at China Geological Survey, told state broadcaster CCTV.

The province is famous for its Karst geological formation.

All caves have formed around an underground river, known as Dingye, which measures 60 kilometres (37 miles) in length and boasts a drop of 292 metres (958 feet).

Some of the sinkholes are located on the altitude of more than 3,208 feet, experts have said

Scientists have spotted primitive vegetation and trees as tall as 164 feet inside the caves

Some of the sinkholes are located on the altitude of more than 1,000 metres (3,208 feet) while others congregate along the underground river 'like a string of beads', according to a statement posted by China's Ministry of Natural Resources on social media.

The Ministry also released footage of experts exploring the exotic world inside the caves.

Scientists have spotted primitive vegetation and trees as tall as 50 metres (164 feet) inside the caves.

The caves are discovered in Napo County in China's Guangxi Province, which borders Vietnam

The world's largest sinkhole cluster is also situated in China.

The Hanzhong sinkhole cluster contains 49 caves. It was discovered in 2016 in the Qinling mountains in north-western China.

The country claims to have the world's deepest underwater cave as well.

Dubbed the 'Dragon Hole', the limestone cave under the South China Sea is 300.89 metres (987 feet) deep. It is nearly the height of The Shard, which is 1,003 feet tall.
