Thein Sein, the acting prime minister, said the final round will discuss elections, political parties, emergency provisions and procedures for constitutional amendments.
 
"This session is the last session," he said.

The talks resumed without the country's leading opposition party, the National League for Democracy (NLD).
 
Despite the boycott, the NLD led by Aung San Suu Ky has submitted proposals for a new charter but received no response.
 
Thein Nyunt, a party spokesman, said they have been sending proposals to the authorities and the public.
 
"We are keeping an eye on the convention and deciding what we should do. We will release our opinion on the constitution when the time comes," he said.
 
Military smokescreen
 
In May, the military extended Suu Kyi's detention for another year.
 
She has spent nearly 12 of the past 17 years under some form of detention.
 
Without Suu Kyi's participation, western governments and other critics say the talks are nothing more than a smokescreen for the military to seal its grip on power.
 
A key objective of the convention was to ensure a "leadership role" for the army in politics, reserving key cabinet positions and 25 per cent of the seats in a future parliament for serving military officers.
 
Brad Adams, Asia director of Human Rights Watch, said in a statement the generals "have trumpeted the convention as a vehicle for a return to civilian rule and the rule of law".
 
"But they have engineered the outcome to ensure the military remains in control and excluded the people of Burma from the process," he added.
 
The military, which has ruled Myanmar since 1962, started the on-off convention process in early 1993 but never committed to a timetable to complete the exercise.
