While countries have begun drawing up lists of luxury items they will deny North Korea in response to the country's nuclear test, the impact has yet to be seen in the handful of stores that sell imported goods in Pyongyang.

During a recent visit, store shelves in the Koryo Hotel in central Pyongyang were well stocked with French perfume, Russian vodka and Japanese sake; restaurants in the North Korean capital still served foreign beer.

Nor were there changes in the exchange rates for the, yen euro or yuan, which have held steady, more or less, at the level of previous months in several hotels that cater to foreign visitors and tourists.
