President Trump told reporters on Thursday that he’ll be looking to impose further financial penalties on North Korea over its nuclear and ballistic tests.

“We will be putting more sanctions on North Korea,” Trump said at a meeting with Afghanistan President Ashraf Ghani at the United Nations.

The remark came in response to a shouted question from a reporter, and the president did not elaborate on whether he would be immediately proposing further sanctions to the U.N. or what the penalties might look like.

The U.N. has passed two resolutions recently aimed at squeezing the North Korean economy by cutting off oil, labor and exports to the nation.
