Kim Jong Un's wife Ri Sol Ju becomes a sensation in China

Kim Jong Un's surprise trip to China this week made headlines, but not just because of its diplomatic relations. The North Korean dictator's meeting with Chinese President Xi Jinping in Beijing was accompanied by Kim's '"mysterious" wife, Ri Sol Ju.

Ri is rarely seen at international diplomatic events, only occasionally at domestic events -- but her appearance this week alongside the two leaders, as well as Xi's wife Peng Liyuan, quickly shot her to stardom in China. To put this into perspective, so little is known about Ri in the international media that her age is reportedly between 28-33. They announced their marriage in 2012 and have three children (we think).

For the two-day trip, Ri was spotted in at least three different outfits by the cameras, all of which received high praise from the social media community.

"Ri Sol-ju is indeed beautiful and amiable. I can tell she would be good at 'first-lady diplomacy', better than Kim's sister," said one commentator on the country's equivalent to Twitter, according to Business Insider. Others said she was prettier than the Chinese first lady, as other praised her conservative yet fashionable attire.

The Chinese government was quick to censor many of these comments.

This was Kim Jong Un's first trip since becoming dictator in 2011, a visit thought to be provoked by the impending meetings with Trump. In early March, Xi Jinping eliminated the two-term limit for presidency, effectively allowing him to serve tenure for life.

"He's now president for life, president for life. And he's great," Trump reportedly responded.
