As Kim Jong Un spent his birthday in Beijing on Tuesday, the young North Korean leader was likely hoping to take home more than just a few gifts during his three-day visit to the Chinese capital.

Kim arrived by special train in Beijing on Tuesday morning for his fourth meeting in less than a year with Chinese President Xi Jinping as talks on plans for a second summit with U.S. President Donald Trump gather steam.

The North Korean leader, who Seoul says was born on Jan. 8, 1984 — though the North's government hasn't officially confirmed the date — met with Xi in China three times last year before and after holding summits with Trump and South Korean President Moon Jae-in.
