Myanmar de facto leader Aung San Suu Kyi's office says she is suffering from weakness and exhaustion after two weeks of travel to Britain and the United States.

The State Counselor office said in a statement Monday that the 71-year-old Suu Kyi's health is stable and nothing to be worried about, but that "she needs to rest."

Suu Kyi arrived back in Yangon on Sunday evening, but was not able to greet supporters waiting outside the airport.

An official from the Ministry of Information said a scheduled meeting between Suu Kyi and Myanmar businessmen on Wednesday had been postponed, without giving further explanation.
