After days of speculation, it has been confirmed that North Korea's leader Kim Jong-un did pay a visit to Beijing.
The visit, confirmed by China and North Korea, was Mr Kim's first known foreign trip since taking office in 2011.
He held "successful talks" with President Xi Jinping, China's Xinhua news agency reported.
China is North Korea's main economic ally and it was thought highly likely it would consult Beijing before planned summits with South Korea and the US.
Mr Kim is due to meet South Korean President Moon Jae-in in April, and US President Donald Trump in May.
The Beijing visit is considered a significant step in North Korea's preparation for the proposed talks.
