Suu Kyi sought the meeting with U.S., British and Australian diplomats to hear their opinions about economic sanctions against the country formerly known as Burma, CNN reported. Details of the meeting weren't immediately available.
"The meeting is a consequence of her letter she submitted to Senior General Than Shwe, she sent on Sept. 25," said Nyan Win, Suu Kyi's lawyer and her political party's spokesman.
A government official also confirmed the meeting, CNN said.
U.S. President Barack Obama's administration has said the so-far unsuccessful sanctions would remain in place. As U.S. officials contemplate moving toward diplomacy, Suu Kyi has called for lifting the sanctions.
Suu Kyi, a Nobel Peace Prize laureate, has been confined in her house for about 14 of the last 20 years. In August, she was sentenced to an additional 18 months of home detention after a military court ruled she violated terms of her house arrest. She was tried on accusations of allowing an American into her home, which she has denied.
