The Latest on the summit in Vietnam between North Korean leader Kim Jong Un and President Donald Trump (all times local):

9:15 a.m.

After barreling through China for three days on his green-and-yellow armored train, North Korean leader Kim Jong Un has switched to another mode of high-security transport after arriving in Vietnam.

He's now traveling in a massive bulletproof Mercedes encircled by bodyguards.

After arriving at Vietnam's Dong Dang Station, Kim shook hands with Vietnamese officials and waved to the crowd before stepping into the limousine. A dozen of crew-cut bodyguards flanked the vehicle and ran in formation as it slowly rolled out of the station and headed to Hanoi, where Kim will meet President Donald Trump for their second summit.

Kim's bodyguards also ran alongside his limousine during his summit with Trump last June in Singapore and his summit with South Korean President Moon Jae-in last April.

Kim Jong Un's train has arrived in Vietnam for the North Korean leader's second summit with Donald Trump.

Vietnamese troops in crisp white uniforms and black boots stood at attention Tuesday to welcome Kim on a red carpet beneath large North Korean and Vietnamese flags at the Dong Dang railway station on the China-Vietnam border. A crowd gathered along the road near the station to wave North Korean flags and bouquets of flowers on a cold, drizzling morning.

It wasn't clear if Kim had visited any places in China on his trip from Pyongyang, the North Korean capital, to the border. Press reports speculate that he will drive the 170 kilometers to Hanoi, the Vietnamese capital, ahead of his Wednesday meeting with Trump..
