SEOUL, South Korea (AP) _ North Korea has issued postage stamps commemorating a June summit with South Korea and depicting the leaders of both countries, officials in Seoul said Thursday, the latest sign of a thaw on the divided peninsula.

The stamp shows a photographic image of the two leaders clasping both hands in a warm greeting at the airport in the North Korean capital Pyongyang, South Korean officials said.

``It appears that North Korea is trying to emphasize the importance of the inter-Korean summit by issuing commemorative postage stamps,'' Seoul's Unification Ministry announced.

Relations between the countries have improved significantly in the wake of the historic summit. The Korean Peninsula was divided in 1945.

In the past, North Korea has issued commemorative stamps to mark the anniversaries of its ruling Workers Party and birthdays of Kim Jong Il and his father, the late former president Kim Il Sung.
