Yangon , Myanmar ( CNN ) -- The younger son of political activist Aung San Suu Kyi arrived in Myanmar on Tuesday for a long-awaited visit with his mother , from whom he 'd been separated for a decade . Kim Aris arrived about 7:30 a.m. Tuesday at the international airport in Yangon , the former national capital , which also is known as Rangoon . Myanmar air force security officials escorted Aris , speeding his arrival without going through standard immigration . Suu Kyi , also escorted by security officials , was quickly able to greet her son . About 100 of her supporters were on hand for Aris 's arrival from Bangkok , Thailand , where he had waited for weeks in limbo for a Myanmar visa . Mother and son left the airport together , bound for her home . It was not immediately clear how long Aris planned to stay in Myanmar . Aris last saw his Nobel Peace Laureate mother in 2000 , when he spent about two weeks with her , according to one of her attorneys . Suu Kyi was released from house arrest on November 13 , after spending most of the past 20 years under house arrest or in prison . Myanmar 's military regime freed her days after holding the country 's first elections in two decades , which critics worldwide dismissed as a sham . The junta 's party declared a landslide victory . Suu Kyi and her National League for Democracy party boycotted the November 7 elections , faulting the military junta . The regime had enacted a new law that forced the NLD to choose between honoring Suu Kyi as its leader and risking the party being declared illegal , or ejecting Suu Kyi from the party and contesting the elections . The NLD won a landslide election victory in 1990 , but the military junta rejected the results . This year , the generals refused to allow international monitors to oversee its elections and overhauled Myanmar 's constitution in a way critics say is aimed at tightening the regime 's grip . The constitution now requires more than 100 military nominees in parliament . Myanmar , also known as Burma , has been under military rule since 1962 . The daughter of Gen. Aung San , a hero of Burmese independence , Suu Kyi has repeatedly challenged Myanmar 's regime over the years . For her efforts , she won the Nobel Peace Prize in 1991 .
They 'd been separated for weeks . Suu Kyi was released from NLD arrest on a decade . The political activist has spent most of the past 20 years under house arrest or in prison . The son had waited in Myanmar , in limbo for a decade , for a Myanmar visa .
