North Korean leader Kim Jong Un's first visit to Russia didn't produce much in the way of substance. But Kim's summit with Russian President Vladimir Putin during that trip gave both world leaders a much-needed PR boost.
Kim's outreach to Moscow comes after his nuclear negotiations with President Trump stalled in Vietnam. The failure of that summit may have bit into Kim's image back home as an international power player, but a chummy meeting with Putin could help restore that.
Meeting with Putin also lets Kim send a signal around the world that North Korea isn't completely isolated, and that engaging with the U.S. doesn't have to be Kim's only way out of punishing international sanctions.
For Putin, a meeting with Kim reasserts Russia's role in the region. The two countries have historically been allies, but Russia didn't have much influence over the recent nuclear negotiations: Putin may be looking to change that.
The two leaders shared similar assessments of how to achieve North Korean denuclearization: gradually, with reciprocal steps from the U.S. But Putin stopped short of offering Kim any concrete relief for his country's struggling economy.
