The cabinet on Tuesday passed a resolution providing for Thailand to impose sanctions against North Korea, as proposed by the Foreign Ministry.
Prime Minister Yingluck Shinawatra said the move follows a request for cooperation by the United Nations.
The UN approved a fresh load of sanctions on March 7 against North Korea for its underground nuclear test in February.
Ms Yingluck said it is Thailand's intention to see regional problems solved through peaceful means.
There are currently no details as to which sanctions Thailand will apply.
