The right-hand man to North Korean leader Kim Jong-un has arrived in New York to discuss a historic summit with US Secretary of State Mike Pompeo.
Gen Kim Yong-chol flew in from the Chinese capital Beijing on an Air China flight.
He is the most senior North Korean to visit the US in nearly 20 years.
President Donald Trump previously cancelled the 12 June summit but both sides have since made fresh efforts to hold it as planned.
Scheduled to happen in Singapore, the historic meeting would be the first between sitting US and North Korean leaders.
Mr Pompeo plans to dine with Gen Kim ahead of talks on Thursday.
US officials have also met North Korean envoys in Panmunjom on the inter-Korean border, while more US diplomats have arrived in Singapore to prepare for the event.
