The following is the Congressional Research Service Insight report, The February Trump-Kim Hanoi Summit
From the report
On February 27 and 28, President Donald Trump and North Korean leader Kim Jong-un met in Hanoi to discuss North Korea’s nuclear and missile programs, as well as the establishment of a new relationship between the two countries. The two leaders had held one prior summit, in Singapore, in June 2018. The Hanoi summit ended earlier than scheduled, with the cancelation of both a lunch and a ceremony to sign a joint statement. President Trump and U.S. officials said that the two leaders parted amicably, and that they expected dialogue would resume at a later date. An article in North Korea’s state-run media also presented the summit in a positive light and mentioned that the two leaders agreed to “continue productive dialogues.” South Korean President Moon Jae-in offered to help the United States and Nort Korea narrow their differences.
The United States and North Korea (Democratic People’s Republic of Korea, DPRK) each attributed the summit’s breakdown to their inability to resolve differences over the scope and sequencing of concessions, specifically DPRK denuclearization measures in exchange for sanctions relief.
