China's President Xi Jinping is in North Korea for a meeting with Kim Jong-un. It is the first Chinese state visit to the North since 2005.
The two leaders, who have met in China four times, are expected to discuss the stalled talks over the North's nuclear programme as well as economic issues. China is important to North Korea, as its main trading
partner.
Mr Xi's two-day visit comes a week before the G20 summit in Japan, where he is set to meet US President Donald Trump.
It will also be his first meeting with Mr Kim since the Trump-Kim meeting at Hanoi in February ended without any agreement on North Korean denuclearisation.
