U.S. President Donald Trump and North Korean leader Kim Jong Un will meet at a luxury hotel on Sentosa Island in Singapore for their June 12 summit, the White House said Tuesday.

The historic meeting, which Washington has said will focus on the denuclearization of the Korean Peninsula, will take place at the Capella Hotel, press secretary Sarah Huckabee Sanders said in a tweet.

The hotel's location is secluded and private, said the Straits Times, a Singaporean paper, quoting experts as saying that such features could be a key consideration for the security-conscious United States and North Korea.

The hotel, together with the Shangri-La Hotel, another luxury establishment in the city state, had been identified as a possible location in the run-up to the summit, the paper said in its online edition.

It will be the first meeting between a sitting U.S. president and a North Korean leader. The former Korean War foes have no diplomatic relations.

A U.S. delegation had been based at the Capella Hotel in Singapore last week during talks with North Korean officials on logistic matters for the summit, according to the paper.

Earlier Tuesday, Trump tweeted, "Meeting in Singapore with North Korea will hopefully be the start of something big...we will soon see!"

Meanwhile, Kim Chang Son, who is often referred to as the North Korean leader's "butler" and led the pre-summit talks with the U.S. delegation in Singapore, arrived in Beijing from the city state by plane on Wednesday.

The arrival of Kim, a senior official of North Korea's State Affairs Commission, suggests that, with logistical matters largely settled, he may be on his way back to North Korea to brief the leader on the contents of the talks.

Kim flew to Singapore from North Korea via Beijing on May 28. While in Singapore, he held talks with such U.S. officials as White House deputy chief of staff Joe Hagin.

Trump had earlier called for the swift and complete surrender of North Korea's nuclear weapons. But he recently softened his position and played down expectations that the issue of the North's nuclear program will be resolved in one meeting.

Last Friday, the president said Singapore would be "a get-to-know-you kind of a situation" and the beginning of "a process" toward the denuclearization of the Korean Peninsula.

Sanders said Monday the upcoming summit will start at 9 a.m. local time.

"We thank our great Singaporean hosts for their hospitality," she tweeted Tuesday.
