The nation is holding an election in a vote broadly rejected as a farce, with key opposition groups banned, numerous figures imprisoned and as much as half of the country unable to participate because of an ongoing civil war.
The ruling junta is holding a staggered election nearly half a decade after it took control in a takeover, which ignited massive protests and spiralled into a devastating conflict.
Observers say the junta, with China's support, is attempting to validate and entrench its power as it seeks a way out of the costly deadlock.
"The environment does not allow for the exercise of the freedoms of free speech, association or peaceful assembly," the United Nations' top human rights official Volker Türk said.
Over two hundred people have been prosecuted for disrupting or criticising 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 prominent figures convicted under the law, which was enacted in July. They were each handed a seven-year jail term after speaking out against a promotional video endorsing the elections.
Civilians are "being coerced from all sides," Mr Türk noted in a statement, adding that resistance forces have made warnings urging people to shun the polls.
The army has been fighting on several fronts, against both armed resistance groups who oppose the coup, as well as ethnic armed organisations which have their own forces. It lost control 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 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 coming weeks in 274 of the country's 330 townships, with the rest deemed not secure enough. Results are expected by late January.
There is unlikely to be any voting in as much as one half of the country. Even in the townships that are voting, some districts will hold elections, making it difficult to predict a likely turnout.
A handful of parties, including the junta-supported Union Solidarity and Development Party, are running nominees nationwide, while another 51 parties and non-aligned contenders will compete only at the state or regional levels.
Approximately forty groups, including Aung San Suu Kyi's National League of Democracy, which scored landslide victories in 2015 and 2020, have been banned. Suu Kyi and a number of the party's senior figures have been jailed under charges broadly viewed as fabricated, while others are in hiding abroad.
"Through dividing the vote into phases, the authorities can adjust tactics if the outcomes in the initial round do not go their way," commented Htin Kyaw Aye, a spokesman of the election-monitoring group Spring Sprouts.
Nations in the West, including the UK and the EU legislature, have dismissed the vote as a pretence, while regional bloc Asean has urged negotiations to precede any election.
The Myanmar regime has dismissed condemnation of the polls, maintaining that it aims to "restore a multi-party democratic system".
"The election is being held for Myanmar. It is being held for the people of this country. It is not intended 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 choose not to participate are rejecting "the path to democracy".
