Secretary of State Mike Pompeo says nuclear negotiations with North Korea will resume quickly following the collapse of President Donald Trump’s summit with Kim Jong Un.

Pompeo tells reporters aboard his plane Thursday that his team will get back to work “tomorrow” although no new meetings have yet been scheduled.

Pompeo said progress was made between Trump and Kim at their talks in Hanoi but not enough to warrant signing any kind of agreement. The White House had scheduled a signing ceremony but abruptly canceled it along with a lunch when it became clear an agreement could not be reached.

Pompeo spoke as he flew to Manila from Hanoi, Vietnam, for talks with senior Philippines officials.
