The joint statement, obtained by Reuters ahead of its planned release this weekend, is a rare declaration by the most senior military commanders from countries around the world, including in Asia and Europe.
It came after news reports and witnesses said Myanmar security forces killed 114 people on Saturday, including some children, on Armed Forces Day – the bloodiest day of its crackdown on pro-democracy protesters since last month’s military coup.
“As chiefs of defence, we condemn the use of lethal force against unarmed people by the Myanmar Armed Forces and associated security services,” read the draft statement.
It was signed by 12 chiefs of defence from Australia, Canada, Denmark, Germany, Greece, Italy, Japan, Netherlands, New Zealand, South Korea, UK and the US.
Diplomats from these countries have already condemned the bloodshed by Myanmar’s military, making the statement largely symbolic. Myanmar’s military have so far ignored criticism of their violent crackdown on dissent.
While the draft statement did not explicitly condemn the Feb 1 coup, which ousted Aung San Suu Kyi’s elected government, it said that a professional military must follow international standards for conduct “and are responsible for protecting – not harming – the people they serve”.
It said the country’s military must “cease violence and work to restore respect and credibility with the people of Myanmar that they have lost through their actions”.
Myanmar’s military have said they took power because November elections won by Suu Kyi’s party were fraudulent, an assertion dismissed by the country’s election commission.
Suu Kyi remains in detention at an undisclosed location and many other figures in her National League for Democracy party are also in custody.
The deaths on Saturday, Myanmar’s annual Armed Forces Day, which commemorates the start of resistance to Japanese occupation in 1945, would take the number of civilians reported killed since the coup to more than 440.
New US and European sanctions this week increased external pressure on the junta. But Myanmar’s generals have enjoyed some support from Russia and China, both veto-holding members of the UN Security Council that could block any potential UN action.
Russia’s deputy defence minister Alexander Fomin attended a parade in Myanmar’s capital Naypyitaw on Saturday, having met senior junta leaders a day earlier.
Diplomats said eight countries – Russia, China, India, Pakistan, Bangladesh, Vietnam, Laos and Thailand – sent representatives to the Armed Forces Day parade, but Russia was the only one to send a minister.
