It is a radical change in the long-repressed Southeast Asian nation that's also known as Burma. Under new rules, journalists will no longer have to submit their work to state censors before publication.
Laws in place since a 1962 military coup gave censors final say in publication. But President Thein Sein's reformist government has been making changes since the end of absolute military rule last year.
Journalists reportedly will still have to submit their articles to the censor board after publication, apparently to allow the government to determine whether any publishing laws are violated.
Those laws include edicts prohibiting journalists from writing articles that could threaten peace and stability, oppose the constitution or insult ethnic groups.
Critics have argued that some laws are open to interpretation and give the government power to go after its critics. The laws have been used in recent years to jail journalists.
