PHOTOS: Kim Jong Un had a grand old time during his surprise visit to China

Kim Jong Un’s first out-of-state trip since coming into power in 2011 was so secretive that China banned all talk of the visit online. But users came up with some nicknames for North Korea’s Supreme Leader to bypass the censorship, like “fatty on the train” and “the obese patient.”

The speculation that Kim was in China for an unannounced visit started when people spotted a train in Beijing on Sunday that was similar to the one Kim’s father used. His presence in China, however, wasn’t confirmed until Tuesday night, when he left.

Kim had, in fact, arrived Sunday via a bulletproof train with his wife, Ri Sol-ju — and lots of lobster and wine, according to the New York Times. A group of senior advisers also accompanied the couple.

Although the visit was unannounced and therefore “unofficial,” Kim’s time in China had the same pomp and circumstance as a normal state visit. The Chinese hosted Kim for a banquet in the Great Hall of the People in Tiananmen Square, complete with honor guards and a gaggle of state media.

Both countries depicted the leaders as allies, and Kim assured Chinese President Xi Jinping that he was committed to giving up nuclear weapons, Chinese state media reported.

Before Kim arrived, China had beefed up its security, which fueled speculation about the visit.

The arrival of a high-ranking North Korean official all but confirmed everyone’s suspicions.

Finally, Kim and his wife arrived in Beijing on March 27 — on a bulletproof, 21-car train, no less. (Kim is reportedly afraid to fly.) Lobster and lots of wine were served while a group of “lady conductors” serenaded the Supreme Leader in Russian and Korean, according to the New York Times.

Kim’s arrival was broadcast across Asia.

The visit was meant to display strong diplomatic ties between China and North Korea. So, naturally, Kim and Chinese President Xi Jinping posed for several photo ops.

North Korean state media, however, portrayed the meeting of the minds quite differently than Chinese state media did. The latter positioned Xi as a wise statesman who was schooling Kim.

But the visit wouldn’t have been complete without some lavish dinner parties.

Kim appeared to enjoy himself.
