Burma rights body urges political prisoners' release
In an letter published in state media, the commission said those who did not "pose a threat to the stability of state" should be freed to help with nation-building, BBC News said.
The commission of scholars and former bureaucrats was only set up last month.
It was part of a series of moves by the government to improve Burma's international reputation.
Burma held its first elections in two decades almost a year ago - polls which saw military rule replaced with a military-backed civilian-led government.
Since then the government has freed pro-democracy leader Aung San Suu Kyi and held dialogue with her.
On Monday a top US diplomat, Kurt Campbell, said the US had noted "dramatic developments under way" in Burma.
He said Washington wanted to see concrete progress on issues like political prisoners - and if it did, the US would match it.
Western nations currently impose sanctions on Burma, and one of the key reasons is political prisoners.
Thought to number more than 2,000, they include journalists, pro-democracy activists, government critics, monks involved in anti-government protests in 2007 and members of Burma's ethnic groups fighting for greater autonomy.
Reports from Burma in recent days, citing unidentified government officials, have suggested a prisoner amnesty could be imminent.
In its letter, the new human rights commission called on President Thein Sein "as a reflection of his magnanimity, to grant amnesty to those prisoners and release them".
