President Biden warned that he would re-impose a Myanmar embargo over the arrest of Aung San Suu Kyi, calling for a joint response from the international community.
"The international community cooperated to pressure, forcing the Myanmar army to immediately give up the power they had conquered and to release arrested officials and activists. The US removed sanctions on Myanmar in the past 10 years.
Biden denounced the Myanmar army's arrest of State Counselor Aung San Suu Kyi, President Win Myint and several senior leaders in the ruling party, saying it was "a direct attack on the transition to the background.
The US President also urged the Myanmar military to lift restrictions on communication, avoiding violent acts against civilians.
The Myanmar situation is the first major test of Biden's commitment to strengthening cooperation with its allies to face international challenges, especially in the context of increasing Chinese influence.
Suu Kyi's ruling National Coalition for Democracy (NLD) won with 346 out of 412 seats in Myanmar's parliament.
The Burmese army on the morning of February 1 arrested Ms. Suu Kyi, President Win Myint and some senior leaders in the NLD party, declaring a state of emergency to run the country for a year.
The US, Australia and the United Nations issued a strong warning message, asking the Myanmar military to release Ms. Suu Kyi and other government officials as well as respect the will of the people and resolve differences through peaceful dialogue.
