U.S. President Joe Biden on Monday threatened to reimpose sanctions on Myanmar’s military leaders after the coup.

A Biden statement condemned the military’s takeover from the civilian-led government on Monday and its detention of elected leader and Nobel laureate Aung San Suu Kyi as “a direct assault on the country’s transition to democracy and the rule of law.”

“The United States removed sanctions on Burma over the past decade based on progress toward democracy. The reversal of that progress will necessitate an immediate review of our sanction laws and authorities, followed by appropriate action,” he said.
