The survivor was among hundreds of hydropower workers who went missing since a tsunami-like wall of water and mud swept through the China-Nepal border following a vast glacial and rock collapse on Aug 26.
Two Nepali hydropower workers were rescued on Friday at the Trishuli 3A tunnel, where searches continued alongside multiple other sites, with at least 12 hydropower projects destroyed by the floods.
So far, 1,344 bodies have been recovered in Nepal, according to the national disaster agency, with around 5,000 people missing.
In China, state media said 31 people had been killed and 531 were missing. That takes the overall death toll to 1,375 people, and more than 5,500 missing.
