U.S. Senator John Kerry is considering a visit to North Korea ahead of a planned meeting between Washington and Pyongyang.

An aide to the senator says he received an invitation from Pyongyang and is planning to visit at an opportune time.

However, the aide added that timing has not been set, while emphasizing that the visit will be to learn about the situation in the communist state rather than to hold negotiations.

Kerry is the chairman of the Senate Foreign Relations Committee.
