The second summit between President Donald Trump and North Korean leader Kim Jong Un will likely be held in Vietnam next month.

Bloomberg reported three places in Vietnam namely capital Hanoi, Danang and Ho Chi Minh City are being considered for the summit.

Following a meeting between Trump and Kim Yong Chol, one of the North Korean leader’s top aides, the White House on Friday said that POTUS would meet Kim in late February.

“Great meeting this week with top Reps. Looking forward to meeting with Chairman Kim at the end of February!” Trump tweeted Sunday.

However, not much is known about what was spoken during Friday’s meeting including what can be expected from the February summit.

Amidst this, Yonhap reported that North Korea's Vice Foreign Minister Choe Son-hui and U.S. Special Representative Stephen Biegun have begun working-level talks to prepare for a second summit over the weekend in Sweden. The talks will continue through Tuesday. South Korea's chief nuclear envoy, Lee Do-hoon, is also a part of the meeting. The U.S. is expected to announce the exact schedule of the second summit post the Sweden meeting.

Meanwhile, U.S. Vice President Mike Pence said that U.S. will be asking North Korea to "take concrete steps to begin to make real the denuclearization that Kim Jong-un committed to” during the second summit.

"And again, the president is very optimistic. The president believes that we can make real progress, and we are going to continue to strive forward,” Pence said in an interview with Fox News.

In an interview with Sinclair Broadcast Group earlier this week, U.S. Secretary of State Mike Pompeo said, “It's the first time a North Korean leader has met with a United States president, looked him in the eye and said I'll do it.”

The two leaders had summit talks in Singapore on Jun.12, 2018 where the North Korean leader agreed to take steps toward denuclearization. However, the talks were stalled after U.S. imposed sanctions on North Korea under it's "maximum pressure" campaign in order to push the latter towards denuclearization.

"There aren't nuclear tests being conducted. There haven't been missile tests conducted. These are things that were threatening the United States when President Trump took office. We want to reduce that risk, reduce North Korea's capacity to build out their program,” Pompeo said.

“We now need to execute. We need to implement. We’ve always known this would be a long process,” he added.
