HANOI, Vietnam (AP) -- With North Korean leader Kim Jong Un on an armored train barreling through China toward Vietnam's capital, and U.S. President Donald Trump about to board a jet for Hanoi, Vietnamese officials scrambled Monday to finish preparation for a rushed summit that will capture global attention.
Officials in Hanoi said they had about 10 days to prepare for the summit -- much less than the nearly two months they said Singapore was given for the first Trump-Kim meeting last year-- but still vowed to provide airtight security for two leaders.
"Security will be at the maximum level," Vietnamese Deputy Minister of Foreign Affairs Le Hoai Trung told reporters at a briefing meant to showcase the nation's efforts to welcome Kim and Trump.
Another official, Nguyen Manh Hung, the leader of the information ministry, said that the 3,000 journalists from 40 countries expected in Hanoi could rely on his agency as "you'd count on a family member."
The world will be watching as Trump and Kim deal with one of Asia's biggest security challenges: North Korea's pursuit of a nuclear program that stands on the verge of viably threatening any target on the planet.
Although many experts are skeptical that Kim will give up the nukes he likely sees as his best guarantee of continued rule, there was a palpable, carnival-like excitement among many in Hanoi as the final preparations were put in place.
T-shirts were being sold that bear Kim's face, along with the phrase "Rocket Man," a nod to the insulting nickname Trump gave Kim in 2017, when North Korean weapons tests and back-and-forth threats by the leaders had many fearing war. Kindergarteners dressed in traditional Korean Hanbok were practicing songs meant to welcome Kim. Grinning tourists were posing in front of the hundreds of U.S. and North Korean flags around the city.
The ultra-tight security will be appreciated by North Korean authorities, who are extremely vigilant about the safety of Kim, the third member of his family to rule the North in absolute power. Kim's decision to take a train, not a plane, may have been influenced by a better ability to control security. When Kim flew to Singapore, the North borrowed a Chinese plane.
Vietnam is eager to show off its huge economic and development improvements since the destruction of the Vietnam War, but the country also tolerates no dissent and is able to provide the kind of firm hand not allowed by more democratic potential hosts.
Take the reaction to two men impersonating Kim and Trump who'd been posing for pictures with curious onlookers ahead of the summit.
Last week, the Kim lookalike, whose name is Lee Howard Ho Wun, posted on Facebook that about 15 police or immigration officers demanded a mandatory "interview" and threatened him with deportation. He said officials later told him that his visa was invalid and he had to leave the country.
"I feel a little bit annoyed," the Hong Kong-based impersonator, who uses the name Howard X, said as he checked out of his hotel. "But what is to be expected of a one-party state with no sense of humor?"
Vietnam has also announced an unprecedented traffic ban along a possible arrival route of for Kim. The Communist Party's Nhan Dan newspaper quoted the Roads Department as saying the ban will affect the 169-kilometer (105-mile) stretch of Highway One from Dong Dang, on the border with China, to Hanoi.
Hundreds of soldiers guarded the area near the Dong Dang railway station Monday ahead of Kim's expected arrival. Kim may get off his train in Dong Dang and finish his journey to Hanoi by car.
There are high expectations for the Hanoi summit after a vague declaration at the first meeting, in June in Singapore, that disappointed many.
Trump, via Twitter, has worked to temper those expectations, predicting before he left for Hanoi a "continuation of the progress" made in Singapore but adding a tantalizing nod to "Denuclearization?" He also said that Kim knows that "without nuclear weapons, his country could fast become one of the great economic powers anywhere in the World."
North Korea has spent decades, at great political and economic sacrifice, building its nuclear program, and there is widespread skepticism among experts that the North will give away that program cheaply.
South Korean media has reported that Trump and Kim might strike a deal that stops short of a hoped-for roadmap for full North Korean denuclearization.
U.S. Secretary of State Mike Pompeo said on "Fox News Sunday" that he was hoping for a "substantive step forward." He cautioned, "it may not happen, but I hope that it will."
