Seoul's Unification Ministry says North Korea's message to South Korea on Thursday contained "inappropriate expressions."  

A ministry official on Friday said Pyongyang asked Seoul in the message to “refrain from comments that cast a damper on the North’s generous proposal.” 

The official said the South Korean government replied with a message through the truce village of Panmunjeom on Friday to say the expression was disrespectful and inappropriate. 

Seoul also told North Korea it hopes the two Koreas will respect each other in the seventh round of talks on the Gaeseong Industrial Complex next week.
