North Korean state media says Russian President Vladimir Putin will arrive in the country on Tuesday for a two-day visit. Putin's first trip to the country in 24 years comes amid international concerns about the two countries' expanding military cooperation. Putin is expected to meet the North Korean leader Kim Jong Un for talks as they deepen their alignment in the face of separate, intensifying confrontations with Washington. North Korea's official Korean Central News Agency said Putin will visit the North on Tuesday and Wednesday at the invitation of Kim. North Korean state media didn't immediately provide more details. Russia confirmed the visit in a simultaneous announcement. Putin also will visit Vietnam.
