Now is a bad time to go to N. Korea:

U.S. bans sales of iPods to N. Korea

Also banned:

cognac, Rolex watches, cigarettes, artwork, expensive cars, Harley Davidson motorcycles, plasma tvs, yachts, or even personal watercraft, such as Jet Skis, ...

The U.N. Security Council voted to ban military supplies and weapons shipments — sanctions already imposed by the United States. It also banned sales of luxury goods but so far has left each country to define such items. Japan included beef, caviar and fatty tuna, along with expensive cars, motorcycles, cameras and more. Many European nations are still working on their lists.

No mention of bananas(?).
