Hillary Clinton has become the first US secretary of state to visit Laos in 57 years.

AFP reports that Clinton landed in the capital Vientiane early on Wednesday morning, and quotes a senior US officials as saying: "It's a pretty big deal for the Laotians."

The last top US diplomat to visit Laos was John Foster Dulles in 1955.
