But there is at least one area in which the two Koreas are showing signs of cooperation -- the Asian Games set to take place in South Korea's Incheon.
North Korea had said it would send a 2-hundred-73 member delegation to the event.
And on Tuesday the two Koreas started discussing related details.
South Korea's unification ministry says it sent a two-page letter to North Korea through the truce village of Panmunjom.
A ministry official says the letter did not contain a direct offer to provide financial support for the North Korean athletes, but added that Seoul will give full support in making sure the athletes don't experience any inconveniences during their time here.
