The nation is holding an election in a vote widely dismissed as a farce, with major political parties dissolved, many of their leaders jailed and as much as half of the country unlikely to vote because of an ongoing civil war.
The ruling junta is holding a phased ballot nearly half a decade after it seized power in a takeover, which sparked massive protests and spiralled into a civil war.
Observers say the military regime, with China's support, is seeking to legitimise and consolidate its power as it looks for a way out of the costly deadlock.
"There are no conditions for the exercise of the rights of freedom of expression, assembly or peaceful assembly," UN High Commissioner for Human Rights Volker Türk said.
More than 200 people have been charged for interfering with or opposing the polls under a recently enacted legislation which imposes harsh penalties, including the death penalty.
Director Mike Tee, actor Kyaw Win Htut and entertainer Ohn Daing were among the well-known individuals found guilty under the law, which was enacted in July. They were each given a prison sentence of seven years after speaking out against a film promoting the elections.
Civilians are "being coerced from all sides," Mr Türk said in a comment, pointing out that armed rebel groups have made warnings urging people to shun the polls.
The army has been engaged on several fronts, against both pro-democracy fighters who reject the coup, as well as ethnic armies which have their own forces. It lost control of large parts of the country in a string of defeats, but regained territory this year following relentless airstrikes made possible through support from China and Russia.
All of this and the fact that significant regions of the country are still under opposition control presents a huge logistical challenge for holding an election.
Voting is set to take place in three phases over the next month in two hundred and seventy-four of the country's 330 townships, with the remainder deemed too unstable. Outcomes are expected by late January.
There is unlikely to be any voting in up to fifty percent of the country. Even in the townships that are voting, not all constituencies will go to the polls, making it difficult to predict a possible turnout.
A handful of parties, including the military-backed Union Solidarity and Development Party, are fielding candidates nationwide, while dozens more parties and independent candidates will compete only at the local levels.
Approximately forty groups, including Aung San Suu Kyi's National League of Democracy, which scored decisive wins in 2015 and 2020, have been dissolved. Suu Kyi and a number of the party's senior figures have been imprisoned under charges broadly viewed as fabricated, while others are in exile.
"By splitting the vote into stages, the authorities can change their approach if the outcomes in the initial round do not go their way," noted Htin Kyaw Aye, a representative of the watchdog group Spring Sprouts.
Nations in the West, including the UK and the EU legislature, have dismissed the vote as a sham, while neighbouring group Asean has called for political dialogue to precede any election.
The Myanmar regime has dismissed criticism of the polls, insisting that it aims to "restore a multi-party democratic system".
"This vote is being held for Myanmar. It is being held for the people of Myanmar. It is not being held for the outside world," a military representative told a news conference last week.
Military leader Min Aung Hlaing cautioned earlier this week that those who refuse to vote are turning their back on "progress toward democracy".
