North Korea’s Kim Jong-un is making a two-day visit to China, a week after meeting US President Donald Trump.
It is expected he will discuss sanctions and the commitment he made at the summit, in general terms, to de-nuclearise the Korean Peninsula.
Beijing, North Korea’s only economic ally, has already suggested sanctions against North Korea could be eased.
Meanwhile, the US and South Korea have confirmed they have suspended planning for their next joint military drills.
That follows a pledge made by Mr Trump at the Singapore summit.
