Vietnam's Top Leader Set for Rare Visit to North Korea in October

Vietnam's top leader, To Lam, is planning a trip to North Korea in October.

This would be a rare visit, as the last time a Vietnamese leader went was almost 20 years ago.

Vietnam and North Korea have friendly relations, but don't trade much.

To Lam recently visited South Korea, which has a tense relationship with North Korea.

This visit highlights Vietnam's existing investment from South Korea.

Details of what will be discussed aren't public yet, but it's a significant event in the countries' diplomatic history.
