The Japanese news agency said Pyongyang's IOC representative Chang Ung made the brief comment to reporters during a stopover at Beijing's international airport.
Kyodo said Chang was believed to be travelling to Switzerland, where the IOC is based.
It quoted unnamed sources saying the trip may be aimed at meeting with the IOC to discuss the North's potential participation in the Games at Pyeongchang.
North Korean leader Kim Jong-Un said in a new year speech that his country wished success for the Olympics, to be held from February 9-25, and would consider sending a delegation.
The two Koreas have been separated by the world's most heavily militarised border since the Korean War ended in a stalemate in 1953.
