The United States has ordered non-emergency government employees and their families to leave Myanmar due to the unrest following the February military coup.
At least 512 civilians have been killed in nearly two months of protests against the coup.
In February, the State Department authorized the voluntary departure of non-emergency personnel from Myanmar. Tuesday's order now makes it mandatory.
US Secretary of State Antony Blinken called on the international community to reconsider their financial support in the country.
Blinken said other nations and companies worldwide should look at pulling "significant investments in enterprises that support the military."
He also described the violence in Myanmar as "reprehensible" and followed a pattern of "increasing disturbing and even horrifying violence" against protestors opposing military rule.
