"Whether it is money laundering, extorting Korean expatriates, or malicious cyber activity, North Korea has engaged in a number of criminal enterprises that helped fund its weapons programs. We must step up our efforts to help to curtail the sources of revenue."

" ...we affirm North Korea's nuclear missile programs as a threat to peace and security in the Asia and Pacific Region. We also affirmed our strong commitment to cooperate, including through the UN, to realize our shared goal of denuclearization of the Korean Peninsula. Meanwhile we'll continue to take necessary measures to defend ourselves and our allies."
 
The meeting came in the wake of the death of Otto Warmbier, who was released by North Korea in a coma after a 17 month detention.
 
U.S. President Donald Trump on Tuesday tweeted that Chinese efforts to reign in Pyongyang did not work.
