An annual report this week by the State Department described "significant human rights issues" in North Korea
Human rights monitors and fleeing Rohingya say the army and Rakhine Buddhist vigilantes have mounted a campaign of arson aimed at driving out the Muslim population.
"In light of the ongoing violence in Burma's Rakhine State, the growing humanitarian crisis it has caused, and our deep concern about the human rights abuses that are taking place, we have decided to suspend the educational courses provided to the Burmese military until there is an acceptable resolution to the current situation," the spokesman said in a statement.
"We call on the Burmese Armed Forces to take immediate steps to stop the violence in Rakhine and ensure the protection of all civilians, to allow full access for humanitarian aid."
