The Associated Press, Yangon | The U.N.'s human rights envoy has arrived in Myanmar on an assessment mission amid much-heralded democratic reforms.

The U.N.'s office in Yangon said Tuesday that Tomas Ojea Quintana will meet government ministers and other parties during his six-day mission. He is also expected to visit the main prison in Yangon and travel to ethnic minority areas.

A prepared statement quoted him saying that his mission was coming during significant developments that mark an important moment in Myanmar's history.
