The announcement of additional aid comes a day after Seoul began shipping emergency food and medical supplies worth $7.5-million to the North, where hundreds have died and around 300,000 have been made homeless in the country's worst flooding since the 1970s.
Seoul's Yohnap news agency quoted Lee as saying: "At a meeting of relevant ministers presided over by the prime minister, they decided to give cement, iron bars, trucks, fuel, road restoration equipment and pitch to North Korea at the earliest possible time,"
The minister said the fuel and materials, urgently needed to restore buildings, bridges, railways and roads damaged by the floods, would be sent as soon as transport could be provided. He said the cost of transporting the materials would total an additional $11 million.
Pyongyang earlier said 11% of the country's rice and corn crop was destroyed by the flooding. Last week the reclusive communist state appealed for international aid.
On Tuesday the United Nations announced an emergency aid program for the North, through which it will deliver around 1,000 metric tons in supplies. Pyongyang has been forced to postpone the second-ever summit with South Korea, which had been scheduled for August 28-30, due to the flooding.
