China says that it had not received official notice from Pyongyang that North Korea was opening its borders to foreigners.
Chinese state broadcaster had on Monday reported that North Korea would allow foreign nationals to enter after more than three years of isolation because of the Covid pandemic.
But the foreign ministry in Beijing said it had not heard from Pyongyang about such a decision.
The CCTV report said the move had been announced by North Korean authorities, but offered no further information about its sourcing.
North Korea is yet to officially announce any border reopening to foreigners.
It has, however, shown signs of a reopening this month, with leader Kim Jong Un travelling to Russia and North Korean athletes travelling to China for the Asian Games.
