SEOUL, South Korea — South Korea announced $7.3 million worth of humanitarian aid for North Korea on Sunday, a conciliatory gesture that coincided with a call by the South for “one last round” of talks on restarting a jointly operated industrial complex.

The majority of the aid — $6 million — will be provided by the South Korean government and shipped through Unicef, the United Nations children’s agency, which provides vaccines, medicine and nutritional supplements for malnourished children and pregnant women in the impoverished North. Five private humanitarian aid groups from South Korea will provide the remainder; they will also send medicine and food for young children.

The South Korean minister in charge of policy toward the North, Ryoo Kihl-jae, said the aid shipments were not linked to political issues. But the announcement was contained in a statement in which Mr. Ryoo also called for a final round of talks with the North to settle disputes over the Kaesong industrial complex, which has been closed since early April.

There was no immediate response from the North Korean government.

The economy in the North remains in dire shape despite international aid and gradual improvements in the North’s grain production in recent years. More than one-quarter of North Korean children under age 5 suffer from chronic malnourishment, according to surveys by the United Nations and international aid groups. South Korean government statistics showed that the North’s infant mortality rates in recent years were several times higher than those in the South.
