The frozen assets correspond to just over SEK 8 billion, and by issuing a so-called presidential decree, the American president rounds off the country's congress.
"Today, I once again demand that the Myanmar military immediately release democratic political leaders and activists whom they now hold captive, such as Aung San Suu Kyi and Win Myint, the president," said Joe Biden.
The military has seized and abducted the country's leader, Peace Prize winner Aung San Suu Kyi, and several members of the government.
Protests have broken out and protesters have been met by both gunfire and water cannons.
Social media has been blocked and the military has also tabled a criticized bill to restrict ISPs and monitor digital traffic, according to Reuters.
Spokesmen for the internet provider Myanmar Net and the mobile operator Telenor tell the news agency that they have not heard of the bill.
The EU wants the UN to condemn
According to Joe Biden, the United States will also restrict trade with Myanmar, and the president is calling on more countries to mark the Myanmar military junta's takeover just over a week ago.
The EU has condemned the coup and called on the military to release detained protesters.
Since 2018, there have been sanctions against Myanmar and according to Reuters, the union also calls on the UN to condemn the coup.
Minorities are persecuted and killed
The military seized power in Myanmar in 1962 and ruled the country until 2010. Minorities such as Muslim Rohingya have been subjected to violent persecution and, according to the UN, generals should be prosecuted for genocide.
