The White House announced Thursday that no deal between the United States and North Korea was reached in Vietnam as President Trump’s second summit with North Korean dictator Kim Jong Un was unexpectedly cut short.

“The two leaders discussed various ways to advance denuclearization and economic driven concepts,” White House press secretary Sarah Sanders said in a statement. “No agreement was reached at this time, but their respective teams look forward to meeting in the future.” She described the meetings between Trump and Kim, which took place Wednesday and Thursday in Hanoi, as “very good and constructive.”
