Nepal Floods Spark Dispute Over Chinese Warnings and Construction
A very large flood hit parts of Nepal near the border with China on August 26.
Water, mud and rocks swept through villages, roads and border facilities.
More than 165 people were reported dead, and 826 were missing in one account.
Some people in Nepal said China should have warned them sooner.
Others claimed construction in Tibet may have changed the landscape and worsened the flood.
China denied these claims.
Chinese officials said an earthquake or glacier collapse caused a landslide and mudslides on the Nepali side.
Both countries were affected, and rescue teams were searching for missing people.
Flash floods struck Nepal’s Bhote Koshi and Trishuli river corridors on August 26.
Reported casualties exceeded 165, while 826 people, including 500 foreign nationals, remained missing.
Nepali reports alleged China failed to provide an early warning after flooding began in Tibet’s Kerung County.
China rejected the allegations, attributing the disaster to an earthquake or glacier-related collapse on the Nepali side.
A barrier lake near the Chhochen Khola and Purepu Tsangpo confluence reportedly reached 2 million cubic meters and posed a breach risk.

Early warning

Cause of the disaster
Critics and Nepali Reports
Some social-media posts and commentators linked the flood to Chinese construction, including settlement and infrastructure activity near the Tibet-Nepal border, although direct links remained unproven.
Chinese Official Position
China said the disaster was caused by a natural earthquake or earthquake-like glacier collapse that triggered a landslide and mudflows on the Nepali side.
Evidence about the trigger
