US bans Myanmar army chief over Rohingya 'ethnic cleansing'

The United States has banned visits by Myanmar's army chief and three other top officers due to their role in the "ethnic cleansing" of the Rohingya minority, urging accountability for their brutal campaign.

The State Department said on Tuesday it took action against army chief Min Aung Hlaing and the others after finding credible evidence they were involved in the violence two years ago that led about 740,000 Rohingya to flee across the border to Bangladesh.

"With this announcement, the United States is the first government to publicly take action with respect to the most senior leadership of the Burmese military," Secretary of State Mike Pompeo said.

"We remain concerned that the Burmese government has taken no actions to hold accountable those responsible for human rights violations and abuses, and there are continued reports of the Burmese military committing human rights violations and abuses throughout the country," he said in a statement.

The sanctions are the most visible sign of U S disappointment with Myanmar, formerly known as Burma, since it launched political reforms in 2011, with the military junta reconciling with Washington and eventually allowing an elected political leadership.

Also sanctioned were Deputy Commander-in-Chief Soe Win, Brigadier General Than Oo and Brigadier General Aung Aung as well as the families of all four officers.

Buddhist-majority Myanmar refuses to grant the mostly Muslim Rohingya citizenship or basic rights and refers to them as "Bengalis," inferring that the Rohingya are illegal immigrants from Bangladesh.

U N investigators say the violence warrants the prosecution of top generals for "genocide" and the International Criminal Court has started a preliminary probe.

Pompeo, issuing a statement during a major meeting at the State Department on religious freedom, repeated the 2017 finding of his predecessor Rex Tillerson that the killings amounted to "ethnic cleansing" while stopping short of using the term genocide.

The sanctions notably do not impact Aung San Suu Kyi, the former political prisoner who has risen to be the top civilian official. The Nobel laureate has dismayed her onetime legions of Western admirers by not speaking out about the abuses.

U S officials voiced hope that the sanctions would help the civilian leaders exert control over the army, which the State Department said was alone responsible for the anti-Rohingya campaign.

"Our hope is that these actions will strengthen the hand of the civilian government (and) will help to further delegitimise the current military leadership," an official said on condition of anonymity.

Erin Murphy, a former State Department official closely involved in the thaw in US ties with Myanmar, said the ban would affect not so much the generals directly but their children or grandchildren who want to come to the United States as tourists or students.

While saying the travel ban provided a tool to encourage change, she doubted it would change attitudes toward the Rohingya, who are "almost a universally despised population."
