The junta first declared a state of emergency after seizing power from the elected government of Aung San Suu Kyi in a coup in February last year, Reuters reported.
Myanmar has been in chaos since then, with conflict spreading after the army crushed mostly peaceful protests in towns and cities.
The 10-member Association of Southeast Asian Nations (ASEAN) agreed a five-point "consensus" to end hostilities last year, but there has been little sign of the junta implementing the five-point plan, which includes an end to violence and dialogue.
Junta leader Min Aung Hlaing said in a speech aired on state media that Myanmar had been striving to overcome the challenges of the Coronavirus pandemic while facing internal violence.
"So it was difficult to implement the ASEAN consensus due to the lack of stability," said Min Aung Hlaing, adding that only when the situation was "normal" could progress be made.
Western governments denounced the coup and the detention on various charges of Suu Kyi and numerous members of her party and supporters.
Some members of ASEAN, of which Myanmar is a member and which has a tradition of non-interference in each other's internal affairs, also criticised the generals.
While the junta has failed to implement the ASEAN plan, it has never rejected it.
"Our country is an ASEAN state so we value the conventions of ASEAN," Min Aung Hlaing said.
While Min Aung Hlaing did not mention the extension of the emergency in his speech, state media reported that a military government defence and security council had unanimously approved his request for six more months.
