South Korea is looking to make its citizens' stomachs the latest front in its standoff with North Korea.

The government in Seoul is telling South Koreans not to eat at the North Korean-run restaurants found in many cities around the world. The goal is to stop money from helping fund Pyongyang's pursuit of nuclear warheads and missiles.

South Korea's Foreign Ministry said Wednesday that South Korean travelers, diplomats and overseas residents have been advised not to go to North Korean restaurants, although such visits are not illegal.

Analysts say Pyongyang probably won't suffer much, as many more Chinese and other nationalities than South Koreans frequent these restaurants.

Washington and Seoul have been calling for more stringent financial and trade sanctions against Pyongyang following its recent nuclear test and rocket launch.
