A convoy of South Korean trucks carrying the first rice-aid to North Korea in three years crossed the peninsula's heavily armed border today in the latest of a series of conciliatory moves between the rivals. At the same time, officials from both countries met in the North Korean border town of Kaesung to discuss the resumption of reunions of families split by the Korean War which were halted after the sinking of a South Korean warship earlier this year. Relations between the two Koreas have soured since conservativePresident Lee Myun-bak's election in 2008, and then sank to their lowest point at the start of the year with the sinking of a South Korean warship, killing 46 sailors.Former US President Jimmy Carter, who visited Pyongyang last month, said the North was now sending a clear and strong signal to Washington and Seoul that it wanted to restart aid-for-disarmament talks.
