The nation is holding an election in a vote broadly rejected as a farce, with key opposition groups dissolved, many of their leaders jailed and a significant portion of the country unlikely to vote because of an continuing civil war.
The ruling junta is conducting a staggered election nearly five years after it seized power in a takeover, which ignited widespread opposition and escalated into a civil war.
Analysts note the junta, with China's support, is seeking to legitimise and entrench its power as it looks for a way out of the devastating stalemate.
"There are no conditions for the exercise of the rights of freedom of expression, association or peaceful protest," UN High Commissioner for Human Rights Volker Türk stated.
More than 200 people have been charged for disrupting or criticising the polls under a recently enacted legislation which carries severe punishments, including the death penalty.
Director Mike Tee, performer Kyaw Win Htut and entertainer Ohn Daing were among the prominent figures found guilty 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 statement, adding that armed rebel groups have issued their own threats urging people to boycott the polls.
The military has been engaged on multiple battlefields, against both pro-democracy fighters who reject the coup, as well as ethnic armed organisations which have their own militias. It ceded territory of large parts of the country in a series of major setbacks, but regained territory this year after relentless airstrikes made possible through support from China and Russia.
All of this and the fact that large parts of the country are still under opposition control presents a massive logistical challenge for conducting an election.
The ballot is set to take place in three phases over the next month in two hundred and seventy-four of the country's three hundred and thirty townships, with the remainder 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, some districts will go to the polls, making it challenging to predict a possible turnout.
Six parties, including the military-backed Union Solidarity and Development Party, are fielding candidates nationwide, while another 51 parties and independent candidates will contest only at the state or regional levels.
Some 40 parties, including Aung San Suu Kyi's National League of Democracy, which scored decisive wins in 2015 and 2020, have been banned. Suu Kyi and many of the party's key leaders have been jailed under charges broadly viewed as fabricated, while the rest are in exile.
"By splitting the vote into stages, the junta can adjust tactics if the results in the first phase 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 European Parliament, have rejected the vote as a sham, while neighbouring group Asean has called for negotiations to come before any election.
The Myanmar regime has dismissed criticism of the polls, insisting 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 citizens of Myanmar. It is not intended for the outside world," a junta spokesman told a briefing last week.
Junta chief Min Aung Hlaing cautioned earlier this week that those who choose not to participate are rejecting "progress toward democracy".
