But since then, General Min Aung Hlaing and the other leaders of Myanmar have escaped international legal wrath. And they are conducting a campaign of denial and avoidance, as well as the detention and intimidation of reporters who have documented the attacks.
On Tuesday, while Myanmar's commander-in-chief in Russia went to arms, Daw Aung San Suu Kyi became a de facto civilian leader, giving a speech in Singapore in which she did not mention the bloodletting of the National Armed Forces. Thousands of Rohingya were said to have been killed in the northern Rakhine state.
But Ms. Aung San Suu Kyi, Nobel Peace Prize winner, has been accused violence against "terrorist activities that were the first cause of events leading to the humanitarian crisis in Rakhine"
On August 25, 2017, Rohingya fighters, mostly armed with improvised weapons, launched strikes on police posts and an army base in northern Rakhine, killing a dozen security forces. Myanmar's military, known as Tatmadaw, says the Rohingya raids were "eviction operations". However, human rights groups have documented how the Tatmadaw sent truckloads of soldiers to North Rakhine in the weeks before the militant strike of 25 August. Soldiers went from house to house, confiscated knives and tore down fencing that could be used by the Rohingya to protect themselves, according to a report by Fortify Rights, a Bangkok-based human rights lawyer.
In a question and after her talk in Singapore, Ms. Aung San Suu Kyi, whose father founded Myanmar's modern army, said the generals in her cabinet were "pretty cute."
Leaving a question of safety concerns aside Rohingya After seeking refuge in Bangladesh, Ms. Aung San Suu Kyi focused on the tourism potential of Rakhine, calling the state "the most beautiful region in Myanmar."
"All the foreigners I've ever met often told me that the beaches in Rakhine State are more attractive than those around the world," she said.
The United States, Canada and the European Union have imposed targeted sanctions on Burmese military, which are believed to have led the gamba against the largely stateless Rohingya last year. But General Min Aung Hlaing and other senior officials were spared.
Others are pushing for an official war crime investigation in Myanmar. On Friday, a group of 132 Southeast Asian legislators called on the United Nations Security Council to refer Myanmar to the International Criminal Court, which decides on genocide and mass crime.
"A year has passed since the Myanmar military launched its killings operation in Rakhine State, but we are not closer to seeing those responsible brought to justice," said Charles Santiago, a member of the Malaysian parliament. "Since Myanmar is obviously both unwilling and unable to investigate itself, we are now at a stage where the international community must intervene to ensure accountability."
Part of the focus on Myanmar's activities was the abolition of entire villages of the Rohingya and the leveling of the landscape, essentially trying to destroy history.
In a recent visit by New York Times journalists to one of these villages in Rakhine State, Myin Hlut, tropical foliage had the former site of human habitation, vines that curl up concrete posts and smother the scorched foundations of homes. The road was lined with charred palm trees and the carcasses of burned out mosques.
A Rohingya born in this village, Zahidullah Rahim, is now a refugee languishing in a camp in Bangladesh. In an interview, he said he once hoped to become a lawyer to represent his people. Now he is still struggling with the idea that the house he once knew was wiped out in an Act of Burmese authorities this year, which was documented by satellite imagery .
"Everything is gone," he said My dreams. "
Since Myanmar has not signed the treaty establishing the International Criminal Court, the Security Council has the power to take legal action, and on Monday the Security Council will discuss the ethnic cleansing in Myanmar
But China and Russia, two permanent members of the Myanmar buys military equipment from both countries, and China has invested heavily in Myanmar's natural resources, particularly in areas where ethnic minorities live, such as the Rakhine state.  General Min Aung Hlaing was at a military forum in Russia last week, and at the beginning of his visit he visited a Moscow exhibition hall with more than 26,000 weapons and other military equipment and enjoyed a "dynamic display" of tanks, aircraft and armored vehicles a Beitra g on his Facebook page.
Myanmar's commander-in-chief thanked Russia for its "cooperation in training and military technology between the two forces, cooperation in counter-terrorism, assistance and assistance to Myanmar in solving the problems in the northern Rakhine state," said the Facebook post.
Myanmar has one of the largest armies in Southeast Asia. A military junta ruled the country for almost half a century and put Ms. Aung San Suu Kyi under house arrest for 15 years.
The current Myanmar government, which consists of a hybrid military-military leadership, has formed half a dozen commissions to investigate the violence in northern Rakhine. But apart from a special case and a handful of redundancies or discouragements, no individuals were held responsible for mass rape, killings and village burnings.
This one case, the massacre of 10 Rohingya men in the village of Inn Din, was documented by Reuters in a February report. Seven soldiers who participated in the executions were sentenced to 10 years in prison. In April, a Burmese television network reported on its website that the men had been released in an amnesty before the news suddenly went offline.
Two of the Reuters journalists reporting on the Inn-Din story are in jail, in court for violating the Myanmar Official Secrets Act. Their verdict is expected on Monday, and they could spend up to 14 years in prison if convicted.
