North Korea has named a sharp-tongued former army officer with little foreign policy experience as its top diplomat, in a possible indication it will take a harder line with Washington in stalled nuclear negotiations. Ri Son Gwon's new title as foreign minister was disclosed Friday in a Korean Central News Agency dispatch that said he attended a reception for foreign diplomats in Pyongyang the previous day. South Korean and other outside media outlets have recently reported North Korea informed foreign diplomats in Pyongyang of Ri's job last week.
