In February 2019, ahead of the 2019 North Korea–United States Hanoi Summit, Markey said that it was "pretty clear that Kim wants to have a personal meeting with Trump with hopes that he can, in fact, elicit concessions from President Trump that might not otherwise be possible if it was just our diplomats talking one-on-one" and that the US "could run the risk that Kim is given concessions which are not accompanied by real concessions that the United States is receiving in return from Kim and his regime." Markey called for Trump to receive commitments on denuclearization from Kim Jong-un before making commitments in return.
