The 27-member bloc imposed travel bans and asset freezes on eight officials and also targeted four "economic entities" tied to the Myanmar military.
What did the EU say about the sanctions?
The EU criticized the officials for "undermining democracy and the rule of law, and for serious human rights violations."
The sanctions on military-controlled companies are intended to hurt the junta financially.
"By targeting the gems and timber sectors, these measures are aimed at restricting the junta's ability to profit from Myanmar's natural resources, while being crafted so as to avoid undue harm to the people of Myanmar," the EU said in a statement.
