The nation is holding an election in a vote broadly rejected as a farce, with major political parties banned, many of their leaders jailed and a significant portion of the country unable to participate because of an continuing internal conflict.
The ruling junta is conducting a staggered election nearly five years after it seized power in a coup, which sparked massive protests and spiralled into a civil war.
Observers say the military regime, with China's support, is attempting to validate and consolidate its power as it seeks a way out of the devastating deadlock.
"There are no conditions for the practice of the freedoms of freedom of expression, assembly or peaceful protest," the United Nations' top human rights official Volker Türk stated.
More than 200 people have been charged for disrupting or opposing the polls under a new law which carries harsh penalties, including the possibility of execution.
Film director Mike Tee, actor Kyaw Win Htut and comedian Ohn Daing were among the prominent figures convicted under the law, which was enacted in July. They were each given a prison sentence of seven years after criticising a film promoting the elections.
Civilians are "facing pressure from all sides," Mr Türk said in a comment, adding that armed rebel groups have issued their own threats asking people to boycott the polls.
The military has been fighting on several fronts, against both armed resistance groups who reject the coup, as well as ethnic armies which have their own militias. It lost control of large parts of the country in a series of major setbacks, but regained territory this year after sustained aerial bombardment enabled by support from China and Russia.
All of this and the fact that significant regions of the country are still under rebel administration presents a huge logistical challenge for conducting an election.
Voting is set to take place in three phases over the next month in 274 of the country's three hundred and thirty townships, with the rest deemed not secure enough. Outcomes are expected by late January.
There is not expected to be any voting in as much as one half of the country. Even in the townships that are voting, not all constituencies will go to the polls, making it challenging to predict a likely turnout.
Six parties, including the military-backed Union Solidarity and Development Party, are running nominees nationwide, while another 51 parties and non-aligned contenders will compete only at the local levels.
Approximately forty groups, including Aung San Suu Kyi's National League of Democracy, which scored landslide victories in 2015 and 2020, have been dissolved. Suu Kyi and a number of the party's key leaders have been imprisoned under charges widely condemned as politically motivated, while others are in hiding abroad.
"By splitting the vote into stages, the junta can change their approach if the outcomes in the initial round do not go their way," commented Htin Kyaw Aye, a representative of the watchdog group Spring Sprouts.
Nations in the West, including the United Kingdom and the European Parliament, have rejected the vote as a sham, while regional bloc Asean has urged political dialogue to precede any election.
The Burmese junta has rejected condemnation of the polls, maintaining that it aims to "return [the country] to a democracy with multiple parties".
"The election is being held for our nation. It is being held for the people of this country. It is not intended for the international community," a military representative told a briefing last week.
Military leader Min Aung Hlaing warned earlier this week that those who refuse to vote are turning their back on "the path to democracy".
