The torch is due to visit five continents before the Games

The flame, which is due to pass through 22 cities in the four months before the Games, is expected to reach North Korean capital Pyongyang on 28 April.

Chinese and North Korean officials made the agreement in Pyongyang, said the official Korean Central News Agency.

A day earlier the torch is scheduled to pass through the South Korean capital of Seoul on its way north, say reports.

The torch, which will be lit at Olympia in Greece on 25 March, is due to cover five continents before the event begins on 8 August.

The planned 137,000-km (85,000-mile) relay route will include a trip to the top of Mount Everest.

The two Koreas have agreed to send a joint team of officials to the Beijing Olympics by train, as part of reconciliation efforts after their 1950-1953 civil war.
