President Donald Trump and North Korean leader Kim Jong Un have arrived in Vietnam for their second summit in less than a year.

The two first met last June in Singapore where they signed an agreement to work to denuclearize the Korean Peninsula. While the agreement called for the end of the North Korean nuclear weapons program, details about the enforcement of the agreement were thin. 

As the two meet again, organizers say the summit will give Trump and Kim a chance to flesh out some more details of the agreement, and perhaps talk about other issues such as declaring an end to the Korean War.

Here’s what to know about the summit:

When and where are they meeting?

Trump and Kim will meet Wednesday and Thursday in Hanoi, Vietnam. Hanoi is in the northern part of the country and its time zone is 12 hours ahead of the Eastern time zone in the United States.

What are they expected to do in this second meeting? 

Trump has praised Kim for ending nuclear missile tests and has appeared to ease up on demanding a timeline for disarmament. According to The Associated Press, Kim is expected to ask for relief from U.S. economic sanctions.

The White House says they expect "to make further progress on the commitments the two leaders made in Singapore – transformed relations, a lasting and stable peace, and the complete denuclearization of the Korean Peninsula."

What has Trump said about what he hopes to come out of the two summits?

Trump has said that "should North Korea follow through on its commitment to complete denuclearization, we will work to ensure there are economic development options. The United States and partners are prepared to explore how to mobilize investment, improve infrastructure, enhance food security, and more in the DPRK," the White House says.

Are there plans for Kim and Trump to meet one-on-one at this summit?

Yes, the two leaders plan to meet privately for 20 minutes.

Does Kim want anything else?
Yes, Kim would like a peace declaration that formally ends the Korean War. While there was an armistice in 1953, the United States and its allies are still at war with North Korea -- at least on paper.
