Two pairs of 3,300-year-old trousers found in China's far western Xinjiang region may be the world's oldest, according to state media.

Archeologists in May found animal-fur menswear on the bodies of two mummies, identified as male shamans in their 40s, the state-run China Daily cited scientists as saying.

An international team is working together to repair and preserve the two pairs, which are the oldest yet discovered with a clear resemblance to modern trousers, the report said.
